Smile on Sky Blue Ramune Day AI Image Prompt

Theme: Sky Blue Ramune Day Subject: A woman in her 20s smiling with a Ramune soda on a midsummer urban building rooftop. Standing slightly to the right of the center in a 2:3 vertical frame, captured from the head to the upper thighs. The person occupies about 70% of the screen, leaving a wide margin of vibrant blue sky at the top. White wireless headphones around the neck, a pale blue drink in a transparent cup, and floating white hand-drawn style musical notes and stars serve as visual accents. Person/Expression: Bright ivory-beige skin with natural pink color and delicate texture. Soft highlights from the summer sun on cheeks, tip of the nose, shoulders, and collarbones. Pale rose-pink blush, champagne beige and pink-brown eye makeup, long thin eyelashes, natural tear bags, soft brown eyebrows, and sheer pink-beige lips. A bright smile with the mouth slightly open, face turned slightly toward the upper left of the screen, and gaze also directed diagonally upward. Small, clear catchlights in the eyes. Hair is bright milk tea ash brown. Thin see-through bangs, layers around the face, medium-long reaching below the shoulders. Hair ends are loosely curled inward, with thin strands and natural wisps swaying slightly in the summer air. Each strand, soft shine, and thin highlights are carefully depicted. Clothing/Pose: A white fine-ribbed square-neck camisole with a translucent thin white shirt draped loosely over the shoulders. Bottoms are light sky blue lightweight shorts with a white drawstring at the waist. A healthy, adult-like natural physique and a calm, feminine silhouette. Holding a transparent cup on the right side of the screen at chest height with her left hand, and lightly bringing the tip of a straw near her lips with her right fingertips. A relaxed standing posture with hips shifted slightly to the left and a slight difference in shoulder height. Accurately depict the contact between fingers, cup, and straw. Background/Light: A rooftop of a building in an urban area of Japan. Metal safety railings in the middle ground, low to mid-rise buildings and thin power lines in the background, with no text or logos. The sky is a highly saturated clear blue with small white cumulus clouds on the left and bottom. Inside the transparent cup are ice, fine carbonated bubbles, and pale light blue Ramune soda, with cold condensation on the cup surface. The main light is harsh daylight from the upper left. Brightly illuminating the cheeks, shoulders, arms, and top of the cup, casting soft shadows under the chin and inside the shirt. Add thin reflections from the blue sky to the skin and white clothes. Composition/Camera: Vertical 2:3 position, a low angle looking up from a slightly low position. Natural perspective equivalent to 35-50mm. Focus accurately on the person's face and lightly blur the background buildings. About 15% margin above the head, with hand-drawn white stars, musical notes, and short lines scattered on the left and right, and a white rough outline placed along the person's silhouette.
