Create a vertical 2:3 black-and-white photographic portrait of a new fictional, clearly adult East Asian woman, age 21, standing close to a bright window between two sheer white curtains. Frame her from the complete crown to the upper thighs, with the figure filling most of the image. Preserve an intimate, quiet pause: her head bends down and slightly toward image left, her gaze lowered, her long wavy hair falling heavily over the shoulder on image right. The face is intentionally in soft deep shadow, not brightly beauty-lit.
Fidelity to the written relationships is the highest priority. Keep the asymmetric open collar of a long white button-front shirt, the narrow dark vertical window mullion just left of her crown, the luminous translucent curtains flanking her body, the downward head angle, the dark flowing hair mass on image right and the subdued monochrome silhouette. The window and cloth should support the person rather than become a large architectural scene.
Her face has a naturally elongated oval outline with adult cheek and jaw planes, gently arched dark brows, downcast almond eyes, a straight softly rounded nose and relaxed closed lips. The tilted brow and cheek remain faintly legible in reflected light; do not erase the features into a flat black patch. Her expression is inward-looking and calm without a camera-facing smile. Keep her head-to-body ratio natural, with a slender adult frame, moderately narrow relaxed shoulders and a believable ribcage. Her shoulders slope gently, and her body stands nearly frontal with a small uneven weight shift. Use only restrained retouching and delicate skin texture.
Her dark hair is loosely gathered high at the back with a little lifted volume at the crown; substantial loose lengths cascade in broad, irregular waves down the right side of the picture to the lower chest. Fine stray hairs near the left cheek catch a little window light. Keep the face partly shaded by her head angle and hair, with the opposite shoulder visually clearer. This is long, flowing hair, not a short bob, uniform curl set or a sleek tight ponytail.
She wears a long, relaxed white cotton button-front shirt with dark small buttons along a central placket, full sleeves and loose cuffs. Several upper buttons are undone, forming a naturally asymmetric V. The left-image collar has slipped outward toward the shoulder, exposing the collarbone and upper shoulder, while the right collar is partly obscured by the falling hair. The remaining buttoned front securely covers the chest and lower torso. Keep the shirt fabric opaque across intimate areas; its light transmission should reveal fabric weight and creases rather than intimate anatomy. Do not add lingerie, lace, jewelry, a belt, logos or an alternative dress. Preserve the roomy shirt's soft vertical fall, the diagonal folds near the waist and a slight opening of the two lower hem panels without explicit exposure.
Both arms hang down naturally beside the body, slightly away from the shirt as the hands rest near the curtains at hip level. Show the relaxed hands within the composition, with plausible fingers, wrists and cloth contact, without lifting the arms or turning the pose into a dramatic gesture. The sleeves bunch gently at the wrists. Let a thin curtain edge overlap a small part of each forearm and the outer shirt silhouette, maintaining a close, layered feeling.
Bright diffused daylight enters from behind through the window. The nearly white curtain panels and window glow surround the dark hair and shadowed head; fine vertical curtain weave remains visible. A narrow dark upright mullion rises behind the head slightly left of center, and a low pale window edge appears at image right. Use broad, soft shadow across the face and upper chest, with gentle reflected illumination on the shirt's folds and cuffs. Preserve the clear light-dark separation without crushing every midtone or adding artificial rim lights. The background has no readable signs or text.
Render neutral monochrome, fine photographic grain, gentle tonal transitions and realistic cotton texture. The mood comes from the lowered gaze, the uneven collar, long loose waves and the luminous curtains closing in on the figure. Keep the quiet domestic simplicity, natural adult anatomy and slight asymmetry. No exaggerated body proportions, explicit nudity, lettering, signature, watermark, border or interface.
