镜面自拍东亚清纯女大学生奶油白针织衫

Subject and Composition: An adult East Asian pure female college student, 3:4 vertical mirror selfie, the character is centered and occupies a large proportion, the upper edge is cut at the neck, the lower edge is cut at the lower part of the white boots, both the head/face and the soles of the shoes are outside the frame.

Pose and Action: The body is slightly turned, with the waist and hips slightly shifted to the right side of the frame. The arm on the left side of the frame is bent at the elbow upwards, holding a brown cartoon pattern mobile phone near the upper left edge; the other elbow is slightly outward, the forearm is raised, and the fingers are relaxed near the shoulder. The legs are close together and not crossed, the left leg in the frame is straighter, the right knee is slightly bent and positioned slightly higher, and the body proportions are natural.

Clothing and Accessories: A cream-colored off-the-shoulder knit sweater, featuring a wide lapel, horizontal openwork herringbone and cable patterns, loose long sleeves covering part of the back of the hand, a cinched waistline, and a small black bow at the center of the neckline. A matching high-waisted vertical ribbed form-fitting mini skirt, a multi-row pearl short necklace with a central teardrop pearl. A small amount of deep brown curly hair falls by the shoulders, rose pink nails, and the upper edge of white boots showing stacked white sock tops.

Scene and Space: On the right side, a black metal window frame and a bright window view, with light blue-gray buildings outside the window; on the left side, the edge of a bed, behind are a wooden folding chair and a dark bag, with the edge of a brown wooden mirror frame visible. The furniture behind and the distant buildings are naturally blurred, retaining the large spatial shapes.

Light and Tone: Slanted sunlight forms large bright spots on the left sleeve, the left side of the skirt, and the leg on the same side in the mirror image; shadows are retained on the chest, shoulders, neck, and the other leg. The highlights outside the window and on parts of the white clothes are close to bright white, with highlights slightly diffusing, and the interior black levels are deep and stable.

Color and Texture: Cream-colored knit, slightly warm skin tone, black bow and window frame, cold blue-gray outside the window. The knit texture is discernible in normally lit areas, while fine lines naturally diminish at the brightest points, maintaining the lifelike quality of a casual selfie.

Image Quality Goal: Clean digital quality, smooth tonal transitions, visible layers in the dark parts within the set brightness, natural and delicate skin with moderate texture.

Follow the above visual requirements, present one and only one small hand-drawn English signature "lyshen" in the bottom right corner of the image, all lowercase, with natural and clear handwriting, not obscuring the main subject.
