Black-and-white artistic portrait of an adult woman

3:4 vertical, photo-realistic black-and-white artistic portrait, low-key studio style, deep gray to black gradient background. A clearly adult fictional East Asian woman, about 22 to 28 years old, facing the camera in left profile and 3/4 back view, framed from top of head to above the chest. Her body is turned to the right side of the frame, head slightly lowered and turned left, eyes naturally closed or lowered, lips gently pressed, expression calm, introspective, slightly melancholic and distant, overall like a film still rather than a commercial pose. She has a delicate soft oval face, natural smooth jawline, slender nose bridge, soft lip shape. Makeup is extremely light, rendered in black-and-white grayscale: fine eyelashes, soft eyeliner, slight under-eye shadow, no emphasis on blush or highlights. Keep real pores, fine vellus hair, subtle skin texture and natural light and shadow, no plastic skin. Dark long hair naturally loosely tied into a low ponytail or low bun, crown slightly loose, multiple fine strands falling around the face and ears, some strands close to the cheeks and neck, back hair merging into shadow. She wears a black high-neck or half-high-neck lace top, shoulders and long sleeves are semi-transparent floral lace, chest and back main body is dark opaque fabric; lace texture is fine, soft, slightly vintage film feel. Use single-side soft light entering from the upper left front of the frame, highlighting forehead, nose bridge, lips, cheekbones, jawline, neck and left shoulder, making the face transition from bright silver gray to deep black. The right side of the face, hair, back and large areas of the body sink into shadow, but still retain faint layering, not dead black. Background is clean with no props, only subtle grayscale separation between the subject silhouette and background. Overall neutral black-and-white silver gelatin print feel, low saturation, low contrast with local deep blacks, high dynamic range, fine grayscale transitions, slight ISO 400 film grain, with Herb Ritts and Peter Lindbergh style restrained portrait quality. 85mm lens, f/2.0-2.8, eye-level slightly high camera position, shallow depth of field, profile, eyelashes, hair strands and lace shoulder sharp, background completely softened. Avoid HDR, over-sharpening, over-smoothing, exaggerated makeup, distorted features, extra limbs, text, logos, watermarks, borders or composites.
