Retrato de Estudio en Claroscuro de Mujer Elegante

A photorealistic vertical portrait of [a young East Asian woman] sitting against a completely black background, illuminated by a narrow dramatic beam of warm light from the upper left. She has [short chestnut-brown bob hair with wispy bangs], smooth natural makeup, large dark eyes, and a subtle shy smile. Facing the camera in a close half-body composition, one hand is raised gently to her lips in a quiet, thoughtful gesture. She is wearing [a sleeveless white satin cheongsam-inspired top with a high Mandarin collar, floral jacquard texture, frog-button closures, and a keyhole neckline]. Emphasize dramatic chiaroscuro lighting: crisp highlights along her face, hair, shoulder, hand, and glossy fabric, with the rest of her body fading into deep shadow. Photorealistic skin texture, soft specular highlights, shallow depth of field, high contrast, elegant cinematic atmosphere.
