Dramatic Chiaroscuro Portrait

Create a photorealistic vertical portrait of {argument name="character name" default="a young East Asian woman"} sitting against a completely black background, lit by a narrow dramatic beam of warm light from the upper left. She has {argument name="hair color and style" default="short chestnut-brown bob hair with wispy bangs"}, smooth natural makeup, large dark eyes, and a subtle shy smile. Pose her facing the camera in a close half-body composition, with one hand raised gently to her lips as if in a quiet, thoughtful moment. She wears {argument name="outfit" default="a sleeveless white satin cheongsam-inspired top with a high Mandarin collar, floral jacquard texture, frog-button closures, and a keyhole neckline"}. Emphasize chiaroscuro lighting: strong highlights on her face, hair, shoulder, hand, and glossy fabric, with the rest of the body fading into deep shadow. Use realistic skin texture, soft specular highlights, shallow depth of field, intimate studio photography mood, high contrast, elegant cinematic atmosphere, vertical 2:3 framing, no text, no watermark, no extra objects.
