 "subject": {
 "description": "A young woman standing on an urban train platform, with a silver train marked by a green stripe rushing past behind her. She is placed in the foreground, slightly right of center, with a realistic fashion street-snapshot feeling.",

 "energy": "not smiling, effortless and composed"
 },
 "overall": "calm, stylish, caught in a brief moment as the train passes behind her"
 },
 "face": {
 "preserve_original": "preserve a small oval face, soft jawline, full natural lips, slightly lifted chin, and the mysterious effect created by sunglasses covering the upper face",
 "makeup": "makeup inspired by East Asian urban Y2K fashion: clean base, nude-pink or rose-mauve lips, subtle contour, polished but understated because the sunglasses obscure the eye makeup"
 }
 },
 "hair": {
 "color": "deep black",
 "style": "long straight hair worn loose, falling over the shoulders, partly swept toward the left by wind or movement",
 "effect": "smooth strands with natural weight, slight motion trail from station airflow"

 "frame": "slim with soft curves, open shoulder and neck line, narrow waist, slightly leaning-back standing posture",
 "waist": "waist and abdomen clearly visible between the cropped top and low-rise jeans",

 "skin": {
 "visible_areas": "visible skin includes the lower half of the face, neck, collarbones, shoulders, upper chest, arms, small underarm-adjacent areas, hands, and waist-abdomen; legs, back, and buttocks are covered or not visible",
 "tone": "light warm beige skin tone with a subtle golden undertone, clean but not pale under cool station lighting and train reflections",
 "texture": "skin appears fine and smooth while retaining realistic street-photo texture, with natural shadows and slight tonal variation on the shoulders, arms, and abdomen; it should feel warm, soft, smooth, and human rather than heavily airbrushed",
 "lighting_effect": "cool-white overhead station lights illuminate the skin from above and slightly front, creating soft highlights on the collarbones, shoulders, chest, and abdomen, while the silver train body adds cool gray reflected light"
 }
 },
 "pose": {
 "position": "standing on the train platform inside the safety area, body facing the camera, head slightly tilted back",
 "base": "one hand hangs naturally near the bag, the other hand lifts to pinch or adjust the hem of the top, body weight shifted slightly to one side",
 "overall": "casual but styled, as if she paused for a quick photo while the train arrived; open shoulders, narrowed waist, and a natural caught-in-motion quality"
 },
 "clothing": {
 "top": {
 "type": "white cropped halter tank top",
 "color": "warm white or cream white",
 "details": "low rounded neckline, halter straps around the neck, fitted ribbed knit or stretch cotton texture, hem ending above the waist",
 "effect": "thin fitted fabric with subtle wrinkles and stretch lines, acting as the bright clean focal point under station lights"
 },
 "bottom": {
 "type": "low-rise loose jeans",
 "color": "vintage gray-brown washed denim",
 "details": "low waistband, relaxed wide legs, heavy washed and worn effect, darker seams and pocket edges",

 "angle": "slightly low-angle close shot from around chest-waist height, looking slightly upward to enhance posture and proportions",
 "shot_type": "vertical half-body to mid-thigh street portrait, subject dominant, moving train as background",
 "aspect_ratio": "4:5 or near vertical social-media street-photo ratio",
 "texture": "real mobile-photo texture, slight wide-angle perspective, natural edge compression and mild noise; subject sharp, background train motion-blurred",
 "lighting": "cool-white fluorescent station lights as the main light, silver train body reflecting cool ambient light, even but metallic urban lighting, no commercial studio fill light",
 "depth_of_field": "subject remains relatively sharp while the fast-moving train behind shows strong horizontal motion blur; station structures remain recognizable"

 "energy": "confident, cool, urban, with a touch of Y2K street-girl attitude",
 "mood": "as if the train had just rushed past and she paused briefly in the wind and noise",
 "aesthetic": "train-platform street snap, white cropped halter top, low-rise vintage denim, black chain bag, gradient sunglasses, layered gold necklaces",
 "authenticity": "keep the real platform environment, train motion blur, slight handheld tilt, phone wide-angle feel, and imperfect casual framing",
 "intimacy": "close shooting distance like a friend’s snapshot, while the subject maintains emotional distance",
 "story": "She was waiting on the platform; the passing train moved her hair as her hand stayed mid-motion adjusting the top hem",
