阳光窗边的戴面具肖像

Create a photorealistic vertical portrait of a young adult East Asian woman sitting indoors beside a bright sunlit window, shown from the chest up in a close three-quarter side profile facing right. She has {argument name="hair color" default="long glossy dark brown hair"}, straight with soft natural layers and a few loose strands catching the light, falling over her shoulder and down her back. She wears a simple {argument name="top color" default="cream white"} sleeveless ribbed knit camisole, with bare shoulders visible and a relaxed seated posture. The face is intentionally obscured by a large centered square privacy mask in a warm brown skin-tone gradient, covering the entire facial area from forehead to chin. The setting is a clean modern room with pale walls, a blue-gray chair partially visible, and a wooden-framed window on the right; outside the window is a softly blurred urban view with daylight. Use warm natural sunlight, backlighting and rim light through the hair, shallow depth of field, realistic skin texture, soft highlights, high-resolution DSLR photography style, intimate lifestyle portrait composition, vertical 4:5 aspect ratio.
