Black and white shot with back to camera

STRICTLY maintain appearance 1:1 — face, features, proportions, shape of eyes and lips, skin texture, hair length and thickness; photo — the only reference. No retouching, no smoothing, no alteration of anatomy. Black and white photorealistic portrait, vertical 3:4 format, tight medium close-up from mid-back and up. Girl stands with her back to the camera, torso turned approximately 60° to the left, open back line. Head turned over shoulder towards the camera, gaze direct, calm, slightly languid. Lips slightly parted, expression confident and soft. Hair gathered in a high ponytail, a few thin strands loosely falling on the forehead and cheeks. Clothing: black minimalist top with thin straps, deep back cut-out. Jewelry — small, smooth earrings without sparkle. Soft diffused light from front and slightly above, low contrast, smooth shadow gradient, light film grain. Background light grey studio, without texture. 85mm, f/2.0, focus strictly on the eyes, hyperrealism, 8K.
