以已上传的成年女性作为唯一的面部身份参考。严格保留她完全可辨认的面部特征——锐利的棕色眼睛、肤色、嘴唇、鼻子、下颌线、面部比例，以及浓密蓬松的…

Use the uploaded adult woman as the sole facial identity reference. Preserve her exact recognizable facial features, piercing brown eyes, skin tone, lips, nose, jawline, facial proportions and long, voluminous brunette hair. Do not alter, beautify or replace her face, and avoid identity drift.
Create an ultra-photorealistic, premium-quality vintage studio portrait of her sitting astride a worn wooden chair, with the back of the chair facing the camera. She leans forward gracefully, resting both elbows on the top rail of the chair. Her fingers are elegantly entwined beneath her chin as she looks directly into the camera with a calm, captivating expression.
She wears a fitted, long-sleeved black top with a tasteful scoop neckline. Her thick brunette curls cascade dramatically around her face and shoulders, with individual strands and natural highlights clearly visible. Make her piercing brown eyes especially sharp and expressive while keeping their original colour.
Use warm, cinematic studio lighting with soft amber highlights, gentle shadows and a subtle vignette. Add delicate vintage film grain, faint aged-photo texture and rich brown tones while maintaining crisp facial detail, realistic skin texture, natural pores and finely rendered eyelashes.
Keep the background plain, softly textured and unobtrusive so the woman remains the sole focal point. Use a centred, intimate medium-close composition with shallow depth of field and a polished high-end editorial finish.
Ensure anatomically correct arms and hands, exactly five natural fingers on each hand, no fused fingers, no extra hands, no extra limbs, no extra toes and no distortions. No text, logos or distracting background objects. Vertical 4:5 portrait, ultra-detailed, cinematic, timeless and flawless 10/10 quality.
