Create a 3:4 vertical minimalist marker-pen travel poster of TOKYO on warm ivory paper. STYLE: Use a rough hand-drawn marker-pen illustration style with thick cobalt-blue contours, broken edges, visible stroke direction, dry-skip texture, and incomplete flat fills. Keep the image graphic, clean, and naturally unfinished. Let the warm ivory paper remain visible in large uncolored areas. TEXT: Add the title "TOKYO" at the top in bold hand-drawn uppercase marker letters, slightly irregular, spontaneous, and organic. SCENE: Depict a storytelling scene on a quiet riverside promenade overlooking the Sumida River. A couple stands near the riverside railing in the lower third, one lightly leaning toward the other.
