Dramatic Chiaroscuro Cinematic Close-Up Portrait

Cinematic close-up portrait of [a beautiful adult woman] with windswept [medium brown hair], with loose strands drifting across her face. She looks upward and to the right with striking light-colored eyes. Composition and camera: square portrait framing, close-up shot, shallow depth of field. Lighting: a sharp diagonal beam of natural light illuminates her cheekbone, nose, eyes, and glossy mauve lips, with the rest of her face and the background falling into deep dramatic shadow, creating a strong chiaroscuro effect. Details and style: fine skin texture, visible hair strands, subtle catchlights in the eyes, soft reflections on the lips, and gentle fabric detail in a lightweight white silk shirt. Mood: mysterious, quiet, introspective, with photorealistic contrast.
