Create a photorealistic smartphone mirror selfie of a beauti

Create a photorealistic smartphone mirror selfie of a beautiful adult South Korean woman in her early 20s. Generate the scene, pose, outfit, hairstyle arrangement, camera angle, and background from scratch. COMPOSITION Vertical 3:4 photograph. The camera is positioned behind the woman, showing her back in the left foreground. A tall, narrow, black-framed rectangular mirror is mounted directly in front of her. Her face appears only as a reflection in the upper-right portion of the image. The back of her head and body remain the main subject. POSE Standing close to a white bathroom vanity, leaning slightly forward with one hand resting on the sink edge. Her back faces the camera, her head turns naturally toward the mirror, and her reflected eyes look at herself. Relaxed shoulders, subtle natural hip shift, realistic posture. HAIR Short black hair gathered into a casual messy updo with a large ivory claw clip. A few loose strands frame her face in the reflection. Keep the hairstyle consistent with a short haircut; do not create long hair. OUTFIT White long-sleeve cropped top with a dramatic open-back cutout exposing most of the back. Thin white straps cross and tie into a bow around the lower back. Fitted white low-rise bottoms with visible seams and a natural waistband. BATHROOM Minimal modern bathroom with a muted gray wall on the left, warm beige stone tiles on the right, and a simple white sink. A small black vanity tray, clear drinking glass, toothpaste, and a few everyday toiletries sit beside the mirror. Warm overhead indoor lighting. CAMERA REALISM Ordinary smartphone photograph with slightly imperfect candid framing, natural skin texture, realistic fabric folds, subtle digital grain, and accurate mirror geometry and perspective. STRICT LAYOUT Back view dominates the left half of the image. The reflected face occupies the upper-right quadrant. The sink and toiletries occupy the lower-right quadrant. One woman only. The reflection must accurately match her actual head position, body orientation, and pose. NEGATIVE PROMPT Front-facing main subject, face directly visible to camera, incorrect reflection, duplicated person, second face, extra limbs, distorted hands, long hair, inconsistent facial features, oversized mirror, elaborate decor, CGI, illustration, watermark, text.
