Portrait en Clair-Obscur sous une Lumière Diagonale

Vertical cinematic portrait of an adult woman wearing a [black fine-rib long-sleeve top with a deep V-neck]. She has a [pale brown straight shoulder-length bob with thin bangs], slender oval face, small chin, downward-looking brown eyes, and plump glossy peach lips, holding a calm expression looking slightly toward the lower left. She wears a [small circular gold pendant on a thin chain]. Her body is angled slightly to the right, framed from the crown to below the chest. Setting & Lighting: Set against a [dark tea-black indoor wall]. A narrow, warm, hard diagonal beam of light enters from the left onto her face, neck, and chest, casting dense, sharp shadows on the wall and beside her cheek. Soft ambient fill from the left background keeps deep shadow areas subtle. Camera & Style: Photorealistic 35mm film aesthetic, sharp focus on eyes, lips, fine hair strands, and ribbed fabric texture, with a gently blurred background. High contrast chiaroscuro mood.
