Chiaroscuro Mauve Lips Portrait

Create an ultra-realistic cinematic 8K close-up portrait of a beautiful adult woman with medium brown hair, slightly wind swept, with loose strands falling across her face. She looks upward and to the right with striking light-colored eyes. A sharp diagonal beam of natural light cuts across her cheekbone, nose, eyes, and glossy mauve lips, while the rest of her face and the background fall into deep dramatic shadow for a strong chiaroscuro effect. Keep the mood mysterious, quiet, and introspective. Show fine skin texture, visible hair strands, subtle reflections in the eyes and lips, and soft detail in a lightweight white silk shirt and dark shoulder shadow. Use shallow depth of field, cinematic contrast, photorealistic detail, and a square portrait composition.
