Korean woman old bookstore spiral staircase portrait

3:4 vertical version, target 1500x2000 pixels, 85mm medium telephoto portrait, the feeling of being observed in the spiral staircase of an old bookstore, low saturation warm gray, shallow depth of field, natural dust light. A clearly adult fictional Korean female, 22–27 years old, soft oval face, clear eyes, long straight black hair naturally flowing down. Clear creamy nude makeup, natural semi-matte base, light apricot blush under the eyes, light pink lips, real pores and fine fuzz visible; quiet but curious gaze. Wearing a dark gray slim-fit knit top, a light gray long skirt, and a loose dark brown long coat, realistic fabric textures and folds. She stands at the corner of a narrow spiral staircase in an old bookstore, one hand resting on the wooden railing, the other holding a closed old book, her body tilted toward the top of the stairs; she looks up at the camera from between the book pages and the railing, with almost no smile on her lips. The lens is like hidden between two foreground book pages, telephoto eye-level close-up, half of the face blurred by the book pages, only one eye, the bridge of the nose, and the lips remain clear; the character is on the right side of the frame, the spiral staircase and bookshelves form a curved background. Afternoon window light enters from above the stairs, falling on the eyes, the narrow line of the bridge of the nose, hair strands, and edges of the book pages, forming soft dust light and shallow depth of field. No minors, no school uniforms, no ancient costumes, no formal commercial poses, no face completely covered, no plastic skin, no full face oily shine, no finger deformities, extra limbs, garbled book pages, logos, watermarks.
