Vertical Studio Half-Body Back View

Vertical studio half-body back view; clearly adult East Asian woman, slender neck and shoulders with natural back lines; sleek loose bun and loose strands at the sides of her face; minimalist black deep-V backless gown; body facing away from camera, head turned to the lower right in profile; black-blue seamless background; narrow soft light from upper front right outlines the nose bridge, shoulders and arms, spine, and hair strands; cool black base with warm skin tones; silent, introspective, sculptural. Final Prompt: Create a vertical minimalist studio realistic art portrait of a clearly adult (approx. 27 years old) East Asian woman standing or sitting with her back to the camera, framed from the top of her head to above the waist. She has a delicate profile, soft straight nose, natural lip line, and lowered eyelashes; her head slowly turns to the right side of the frame and looks slightly downward, not looking at the camera, with a calm, introspective, slightly distant mood. Dark brown-black hair is combed into a sleek but not stiff loose bun, full at the back of the head, with a few fine wisps kept at the edges of the bun and the sides of her face. She wears a minimalist matte black sleeveless gown with wider shoulder straps, and the back has a very deep symmetrical V-shaped opening that gathers from between the shoulder blades toward the waist, fully covering the front of her body; her slender neck, natural shoulder blades, shallow spinal groove, and soft back texture are exposed. Her pose is slightly twisted, one shoulder closer to the camera, right arm falling along her body, with the back and arm forming a quiet triangular composition. The background is a textureless deep black-blue studio seamless backdrop. The only key light falls from the upper front right of the frame as a narrow soft beam, illuminating the profile, nose bridge, lower lip, right shoulder, and upper arm, and forming a thin warm rim light along the bun and stray hair strands; the center of the back is in soft midtone, while the left side quickly merges into deep black shadow. Controlled highlights without overexposure, warm natural skin tone, and the black dress separated from the background by a subtle brightness difference. Medium-shallow depth of field, focus covering the profile, shoulder line, and upper back, realistic skin texture and fine hair strands, low saturation, deep blacks, slight film grain, no plastic skin, no jewelry, no text, no logo, no watermark.
