Cinematic film-style portrait with dark studio atmosphere

Locked: clearly adult age 20; East Asian downward profile; fringe concealing the eyes; loose bun; tiny hoop; both hands gathering an opaque white shirt closed; exposed shoulders; black background; diagonal hard light; intimate 9:16 crop. Create a vertical 9:16 cinematic chiaroscuro portrait of a clearly adult 20-year-old East Asian woman with delicate, playful adult charm and refined East Asian beauty. She has a soft oval face, a slender natural jaw, a small rounded chin, a fine straight nose, softly defined lips, and pale neutral skin with authentic texture. Her dark brown hair is loosely pinned into an imperfect bun, with a long airy fringe and several damp-looking flyaway strands falling across her forehead, eyes, cheek, and neck. A tiny plain silver hoop is visible on one ear. Compose a close three-quarter standing portrait from the top of her head to below the hips. Her body angles slightly left while her face turns down and toward frame right; her eyes remain hidden beneath the fringe and her lips are gently parted. Both shoulders are relaxed and bare. She wears a single oversized white cotton button-up shirt slipped naturally from both shoulders. With both hands centered high at the sternum, she carefully gathers and holds the shirt fronts closed; the fabric is fully opaque, doubled where necessary, and securely covers the bust and torso. Her slim fingers overlap softly, with believable joints, nails, pressure, and cloth contact. Preserve her natural slender adult proportions without enlargement, slimming, flattening, or idealized reshaping. PRIMARY VISUAL LINE: the descending line from shadowed face through neck and collarbones to the covered shoulder line. Make it readable through the low off-shoulder collar, downward head angle, inward hand gesture, realistic gravity in the oversized shirt, and a bright diagonal light plane. Keep the face and hands perceptually dominant; do not center the composition on anatomy. Use a nearly black studio-like interior with no visible furniture. A narrow, hard beam of warm-white light enters from upper frame right, striking the fringe, nose bridge, lips, one clavicle, upper chest, hands, and selected folds of the white sleeve while the back of the head and left side dissolve into deep black. Preserve crisp cast shadows from fingers and hair, luminous skin grain, high contrast, subtle film texture, restrained color, and rapid falloff without beauty fill. FIDELITY — HIGHEST PRIORITY: preserve the stated facial geometry, downward hidden-eye expression, loose bun and veil-like fringe, tiny hoop earring, natural body proportions, exact oversized off-shoulder white shirt and both hands gathering it securely closed, head and shoulder geometry, tall close crop, single diagonal hard-light signature, black background, and private contemplative atmosphere. Apply only the stated age of 20; do not otherwise redesign, beautify, enlarge the eyes, narrow the waist, enlarge or suppress curves, change the wardrobe, or alter the mood.
