"subject": {
"description": "An unmistakably adult young woman seated in the dark rear seat of a car, taking a close-range handheld selfie. Her body runs diagonally through most of the frame, with very long black hair spilling over her shoulders, chest, and the seat. A black-and-white polka-dot hat, matching two-piece outfit, butterfly choker, pearls, and metallic jewelry create a distinctive Y2K, Japanese street-fashion, slightly gyaru-adjacent styling language. It should feel like a private snapshot taken in transit rather than a polished commercial fashion shoot.",
"mirror_rules": "This is not a mirror selfie; it reads as a front-facing smartphone or one-handed phone selfie. Preserve the relationship between the raised hand, low hat brim, window side, and diagonal body direction instead of automatically mirroring or correcting everything into conventional portrait symmetry.",
"age": "Clearly adult young woman, visually around her twenties; maintain an unmistakably adult appearance.",
"expression": {
"eyes": {
"look": "The eyes are partially hidden by both the low hat brim and the raised hand. The visible eye area has defined dark eyeliner and noticeable lashes, directed toward the phone.",
"energy": "Quiet, playful, slightly detached.",
"direction": "Toward the close phone camera, with one side of the eye area partially covered by the hand."
},
"mouth": {
"position": "Lips pushed slightly forward into a restrained natural pout.",
"energy": "Relaxed and controlled rather than exaggerated."
},
"overall": "She looks posed but not fully formal, retaining the loose, private feeling of a spontaneous personal selfie."
},
"face": {
"preserve_original": "Preserve the relatively slim facial contour, the partial concealment created by the low hat brim, and the way long strands of hair sit close to both sides of the face. Avoid excessive facial symmetry, hyper-sharpening, or commercial beauty retouching.",
"makeup": "Use a refined Y2K Japanese street-fashion / Harajuku / lightly gyaru-adjacent beauty direction: defined black upper eyeliner, elongated lashes, subtly deepened eye area, translucent base makeup with natural skin variation, and glossy semi-transparent rose-pink or nude-pink lips. Do not assign race, nationality, or ethnicity."
}
},
"hair": {
"color": "Deep black.",
"style": "Extremely long straight hair, center or near-center parted, with a few thin strands falling naturally across the cheeks, collarbones, and chest while the rest spreads over the shoulder and car seat.",
"effect": "Mostly straight and smooth but not advertising-perfect; retain fine flyaways, slight irregularity, realistic weight, soft cool highlights near the window, and deep blacks in shadow."
},
"body": {
"frame": "Slim, elongated adult feminine frame with light shoulder and neck lines, arranged diagonally by the seated posture.",
"waist": "Narrow waist with the abdomen naturally relaxed rather than aggressively sucked in; realistic seated curvature.",
"chest": "A broad area of upper chest and collarbone remains visible while the polka-dot top covers and supports the bust. Keep realistic proportions without artificial enlargement or exaggerated compression.",
"legs": "The frame mainly shows the hips and upper thighs. One thigh is closer to the camera and occupies a larger foreground area, creating subtle smartphone wide-angle perspective.",
"skin": {
"visible_areas": "Visible skin includes the face, neck, collarbones, shoulders, upper chest and surrounding décolletage, upper arms, forearms, hands and fingers, abdomen, waist sides, hips, and upper thighs. The main bust area and central pelvic area remain covered by clothing. A few natural small moles or pigmentation marks are visible on the abdomen.",
"tone": "Fair-light skin with a neutral-to-slightly-warm undertone, picking up subtle pinkness and soft highlights from the daylight entering through the window.",
"texture": "Skin should look fine, soft, and slightly satin-like to the touch, while still retaining tiny pores, gentle tonal variation, natural body contours, and small moles. Avoid waxy or plastic smoothing.",
"lighting_effect": "Real daylight entering from the window on frame-right forms a broad soft source across the arm, hand, upper chest, abdomen, and thigh. Highlights transition gradually while areas farther from the window sink naturally into the dark car interior. The arm and thigh catch more light because they are closer to the window, while the hat brim casts a physical shadow over the upper face."
}
},
"pose": {
"position": "She is seated or half-reclined in the black rear car seat, upper body leaning toward frame-left and the camera while the hips and thighs extend toward the lower-right.",
"base": "Most body weight rests against the rear seat and backrest. One arm reaches out of frame to hold the phone, while the other hand is raised in front of the face.",
"overall": "The raised hand sits horizontally near the eye and cheek, fingers naturally spread to display long nail art while partially covering the face. The pose is self-aware but the shoulders, waist, and legs remain relaxed and asymmetrical."
},
"clothing": {
"top": {
"type": "Black thin-strap bikini / bra-style top with a low balconette-like or simple swimwear silhouette.",
"color": "Black with irregular white polka dots.",
"details": "Thin straps, body-hugging fabric, slightly varied white dot sizes, and a low neckline exposing the collarbones and upper chest.",
"effect": "Close-fitting fabric with realistic tension and minor folds; avoid latex sheen or perfectly wrinkle-free CGI fabric."
},
"bottom": {
"type": "Matching low-rise, high-cut bikini-style bottom.",
"color": "Black with white polka dots.",
"details": "Low waistline with narrow side sections, revealing much of the hips and upper thighs while maintaining realistic garment coverage and fabric tension."
}
},
"accessories": {
"headwear": "A soft black bucket-hat or low-brim hat covered in small white dots, worn low enough for the brim to obscure part of the forehead and eyes.",
"jewelry": "A short pearl-like necklace around the neck with a dimensional black butterfly centerpiece, plus a longer fine chain carrying a small silver flower or clover-like pendant. A very thin metallic waist chain crosses the abdomen with a small dangling charm near the center.",
"prop": "A partially cropped pink elongated handheld object appears at the lower-left, decorated with illustrated or ornamental details and a slightly rounded textured end. Its exact function is unclear, so reproduce it only as an ambiguous cropped foreground prop rather than assigning a specific identity."
},
"photography": {
"camera_style": "Authentic smartphone front-camera selfie, approximately a modern 24–28mm full-frame-equivalent wide field of view. Not a professional studio portrait. Mild computational exposure correction may brighten the skin, but no obvious portrait-mode blur.",
"angle": "The phone sits slightly above and in front of the face, offset to one side, pointing downward at a mild oblique angle. The close wide-angle distance produces subtle enlargement of foreground elements such as the hand, arm, and thigh.",
"shot_type": "Close seated selfie / casual car portrait between a half-body and three-quarter-body crop. The subject is not perfectly centered. Her body runs from upper-left to lower-right, with natural cropping around the hat, hair, and legs.",
"aspect_ratio": "1:1 square social-media photograph.",
"texture": "Retain mild smartphone JPEG or social-media compression, faint grain, slight computational sharpening, and imperfect edges. Avoid immaculate commercial retouching.",
"lighting": "The primary source is natural daytime light entering from the window at upper frame-right, creating a broad soft side light. No obvious flash, rim light, or professional fill. The dark leather seats and interior act as natural negative fill, deepening the opposite side of the body and hair. The exterior through the window is close to overexposed while the subject retains moderate highlight detail.",
"depth_of_field": "Relatively deep depth of field typical of a small-sensor smartphone wide lens, keeping the face, hand, upper body, and much of the car interior reasonably sharp. Only very mild distance softness; no exaggerated f/1.2-style creamy bokeh."

"background": {
"setting": "Modern car rear-seat interior.",
"wall_color": "Predominantly black and charcoal leather and door trim.",
"elements": [
"black perforated leather seat and backrest",
"dark door panel with pale stitching",
"right-side car window and window frame",
"bright sunlit pavement or roadside surface outside",
"a small amount of light-colored fabric or clothing casually gathered near the bottom of the seat"
],
"atmosphere": "The enclosed dark car interior contrasts with the bright exterior, creating a private, temporary, in-transit feeling.",
"lighting": "The cabin itself stays dim and depends mostly on single-sided window daylight. Keep the exterior much brighter than the interior; do not introduce roof lights, colorful ambient LEDs, or studio rim lighting."
},
"the_vibe": {
"energy": "Low-key, confident, languid, slightly playful.",
"mood": "It feels as though she had just gotten into the car and casually taken the photo; the preceding movement is already over, but its emotional residue remains in the pose.",
"aesthetic": "Y2K, Japanese street fashion, retro polka dots, lightly gyaru-adjacent, private social-media selfie rather than luxury fashion advertising.",
"authenticity": "Allow the hat to block the eyes, hair to fall imperfectly, background clutter to remain, fingers to interrupt the face, wide-angle proportion shifts, and a slightly unbalanced crop. These accidents are part of the image identity.",
"intimacy": "Close in distance without feeling like a formal invitation; more like a private moment where the front camera was opened unexpectedly.",
"story": "She seems to have just adjusted her hat and hair after sitting down in the car. Her hand is still suspended beside her face, as though it will drop a second later, but the photo preserves that unfinished gesture.",
"caption_energy": "Very low-information social post: a tiny status line, a symbol, or no caption at all."
