Preserve the reference photo subject's facial features, bone structure, eye shape, skin texture, and hair appearance 100%, maintaining complete resemblance. A photorealistic candid shot captured in motion, [close-up, waist-up framing]. The [woman] stands with her back to the camera at the exact moment she sharply turns her head over her shoulder, gazing off to the side with an authentic, unposed expression. The rapid head turn produces natural motion blur across the hair strands and slight softening along silhouette contours, while her facial identity remains clearly recognizable. Body posture shows realistic tension and asymmetry in the shoulders and neck. Shot on 35mm film aesthetic with cinematic directional lighting, soft shadows, pronounced film grain, low-saturation muted tones, subtle optical imperfections, and realistic skin texture with visible pores.
