Theme:
Blue room before bed

Person/Expression:
An adult woman who looks like she is in her late 20s. Mature and steady physique, exuding an elegant atmosphere without childishness. Skin is bright ivory beige-toned fair skin with a faint pink flush, smooth and delicate texture. No excessive highlights or whiteness; soft highlights on the cheeks, tip of the nose, shoulders, and collarbone, with moderate pore texture that doesn't look unnaturally plastic. Faint rose pink blush on the cheeks, champagne beige and pink brown gradient makeup on the eyes. Long and natural eyelashes, natural eye bags, bright brown soft arched eyebrows. Lips have translucent pink beige lip gloss, naturally shining in the center. The overall facial makeup is an elegant and clean precision doll-style Japanese makeup. Hair is deep brown almost black long hair, keeping thin bangs and stray strands around the face. The head is tilted slightly to the lower left, gaze falling slightly in front of the hands. Expression is serene and peaceful, with a soft lingering afterglow of before falling asleep.

Clothing/Pose:
Summer night ivory-colored cool-feeling loungewear. The top is a short camisole-style top with thin straps and delicate lace edges; the top few front buttons are undone, forming a deep V-neckline. The fabric opens naturally and softly, but the exposed parts are elegant and restrained. The bottom consists of matching shorts with ruffles and a thin ribbon tied at the waist. Sitting on the bed in a side-sitting posture close to the original image. The leg on the left side of the screen is bent and extended forward, while the leg on the right side of the screen is deeply bent and folded to the side. The upper body leans slightly forward with shoulders pulled inward. Both arms hang naturally in front of the body, hands gently stacked on the bed surface between the knees. Five fingers on each hand are naturally visible, fingertips relaxed and aligned. Natural indentations and contact shadows are added where the skin, clothing, and bed meet.

Background/Lighting:
A night apartment bedroom. To the left of the screen is a large window and thin curtains; outside is a deep blue night scene, with distant streetlights forming small blurred points of light. To the back right of the screen is a warm-toned bedside lamp and a small potted plant. The bed is covered with light gray sheets and white pillows; the whole room is clean and quiet. Cold blue night light casts in from the window side, outlining the hair and shoulders, while the lamp in the back right casts warm light, softly illuminating the cheeks, collarbone, arms, and clothing fabric. Shadows fall elegantly in front of the bed and at the bottom left of the screen, with the blue and orange light blending naturally.

Composition/Lens:
Vertical 4:5. Close-up indoor portrait from the head to the thighs and tips of the knees. The person is located slightly to the right of the center of the screen, focusing on the hands and upper body. The camera is slightly higher than the bed for a slight high-angle shot, with the line of sight almost level with the eyes. Natural compression feeling close to a medium-long focal length, focusing on the texture of the face, collarbone, hands, and loungewear. The background window, curtains, and lamps are softly blurred, preserving the sense of depth of the night.

Texture/Style:
Realistic photo-style AI image. Night indoor portrait, with a steady texture like a Japanese lifestyle photo. Skin is smooth but not over-retouched, retaining natural texture and color. Detailed depiction of the texture of thin cotton ribbing, lace, ruffles, and ribbons of the clothing. Color tones are mainly ivory, light beige, deep navy blue, and warm lamp colors. Low to medium contrast, soft grain, creating a clean and intimate night atmosphere.
