Use case: photorealistic-natural. Create one original cinematic acting reference portrait, landscape 16:9. A fictional adult East Asian woman in her early thirties, short chestnut bob tucked behind one ear, dark brown eyes, natural unretouched skin, plain ochre cardigan over a cream round-neck top. Eye-level chest-up portrait, head and shoulders fully visible, near-frontal three-quarter turn only 10 degrees. Soft warm window light from camera left, quiet blurred warm-gray studio background, fixed moderate portrait perspective, natural skin and realistic eyes and teeth. No text, labels, watermark, collage, jewelry or recognizable real person. Expression and situation: A gentle restrained closed-mouth smile. Mouth corners rise slightly and symmetrically, cheeks lift softly, eyes are relaxed and warmly attentive. A quiet hello to someone she trusts.
