 "full_string": "Hyper-realistic 8K matte-filmic street portrait. Replace the woman with the uploaded subject while keeping the exact same walking pose, stride, arm swing, outfit structure, camera angle, lighting, background layout, and muted color grading. Scene: woman walking confidently down a quiet urban street, mid-stride. Body facing forward, torso upright, left leg stepping forward, right leg slightly behind. Arms swinging naturally with the motion—right arm extended back slightly, left arm slightly forward. Head facing forward with subtle hair movement. Expression calm, confident, neutral. Wardrobe: cropped mustard-yellow tee featuring a CLEAR, AUTHENTIC VANS LOGO printed on the chest; shirt is slightly loose and lifted by motion. High-waisted, bright blue distressed skinny jeans with extreme shredding across thighs and knees. Black-and-white Vans checkerboard slip-on shoes. Lighting: soft overcast daylight with smooth skin tones and low contrast shadows. Color grading: muted greens, matte yellows, subtle blues, vintage film texture, soft grain, slight vignette, Kodak Vision3/CineStill inspired tones. Background: parked cars along both sides, dark green chain-link fence on the left, tall muted trees, sidewalk and curb visible. Depth of field: medium-shallow—subject sharply focused, background softly blurred but clear enough to identify. Camera: eye-level, medium-full body portrait, telephoto-leaning focal length (70–105mm equivalent). Composition: subject centered, walking toward camera, shot straight down the street. The Vans logo MUST remain visible, well-proportioned, and realistically integrated into the tee’s fabric behavior. --ar 4:5 --style raw --v 6.0",
