女性在台阶上的写实竖构图肖像

Create a realistic vertical 9:16 photographed portrait. Subject and action: one adult woman seated alone on the steps, compactly folded forward beneath the camera, looking upward while resting her face on one hand. Hair and styling: a chin-length rounded bob with a brow-clear side fringe, in deep chocolate brown; jaw-to-collarbone bob/lob/compact-tie geometry; borrow from source text only motion/contact behavior such as wind, pillow spread, wetness, or a cap/collar tuck. Composition: vertical full-body seated portrait from a steep high angle, shot close from above with a slightly wide phone lens; her body runs diagonally from upper left to lower center, face clearly readable, concrete steps filling the frame, black rectangular street pole near the upper. Camera: handheld smartphone viewpoint from standing height above her, downward tilt around 55 degrees, deep focus, mild wide-angle spatial stretch, slightly crooked casual framing. Color and depth relationships: cool blue-grey concrete and pale washed denim dominate, anchored by near-black outfit elements, with warm sunlit skin as the only warm color. Pose: head tilted into the supporting palm, eyes looking directly up into the camera, eyelids slightly narrowed, brows relaxed, lips closed in a soft neutral pout. Wardrobe: fitted black spaghetti-strap camisole with a low straight neckline; loose low-rise pale grey-blue acid-washed jeans with heavy. Setting: outdoor urban concrete stairway beside dark asphalt; broad ribbed grey step surface on the left, rough concrete risers and curb beneath her, weathered pavement with stains and chips, and a narrow black metal pole rising behind her. Lighting: natural daylight from the upper left, moderately hard and uneven; warm highlights across the forehead, cheek, shoulder and forearm, with soft open shadows beneath the chin, arm and body; no flash. Natural snapshot details: keep the awkward steep overhead angle, slightly tilted framing, uneven daylight across the face and shoulder, pavement scuffs and stains, the near foot partly obscured by the bent legs, and minor phone softness around. Finish: natural available light, realistic skin texture, and restrained photographic processing. Skin and material texture: unretouched photographed skin with visible pores, vellus hair, under-eye/lip texture, tonal variation, and faint grain on face, neck, ears, and hands, including flash, monochrome, and low light; Local microtexture on face, neck, ears, and hands must be explicitly rendered. Rendering constraints: keep the exact crop, body-to-camera relationship, hand task, gaze direction, light direction, foreground obstruction, and background placement; preserve believable anatomy and natural hands; avoid beauty-filter skin, studio-clean restaging, generic fashion posing, text, logos, borders, and watermarks.
