超写实街头风人像，保留面部特征

An amateur street-style photo taken on an iPhone rear camera. Use the uploaded face as the ONLY and EXACT facial reference - preserve facial geometry, proportions, likeness and age 1:1. Do not alter facial features even by 1%. No beautification, no stylization. Framing & angle: medium shot, camera slightly above waist level, close to the subject, natural iPhone perspective, subject centered. Pose: model sitting on a low wooden platform, torso slightly leaning back, both hands resting behind on the surface for support, shoulders relaxed, head slightly tilted downward and turned to the side, calm grounded posture. Scene: urban skatepark or street-art zone, colorful graffiti walls, layered paint textures, metal structures in background, raw city atmosphere, street culture environment. Outfit: matte dark oversized T-shirt, loose black cargo pants, textured olive-green suede or matte canvas jacket, minimal belt detail, streetwear styling, visible stitching and fabric structure. Emotion: serious, introspective expression, quiet confidence, relaxed street attitude. Lighting: natural overcast daylight, soft diffused light, gentle shadows, no flash, cinematic but realistic contrast. Skin realism: hyper-realistic skin texture, visible pores, subtle imperfections, natural skin tone variation. Hair: natural hairline, individual strands visible, soft texture. Hands: natural skin texture, realistic shading across knuckles and fingers. Textures: worn graffiti wall surface, chipped paint, rough concrete floor, matte fabric fibers, jacket material texture. Camera look: authentic iPhone photo, sharp focus on subject, mild digital noise, natural color tones, unedited iPhone RAW feel, high realism, 3:4 format.
