Summer Breeze Soda Portrait on City Rooftop

Subject: Sky-blue Ramune Day Main Subject: A woman in her 20s laughing with a ramune soda in her hand on a city building rooftop in midsummer. She stands slightly to the right of the center in a vertical 2:3 frame, captured from head to upper thighs. The person occupies about 70% of the screen, leaving a wide margin of vivid blue sky at the top. Visual accents include white wireless headphones around her neck, a pale blue drink in a transparent cup, and hand-drawn style white musical notes and stars floating around her. Person & Expression: Bright ivory-beige skin with natural pink coloration and delicate skin texture. Soft highlights from the summer sun on the cheeks, tip of the nose, shoulders, and collarbones. Pale rose-pink blush, champagne beige and pink-brown eye makeup, long slender eyelashes, natural tear bags, soft brown eyebrows, and translucent pink-beige lips. A bright smile with the mouth slightly open, face turned lightly toward the upper left of the screen, and gaze directed diagonally upward. Small, clear catchlights in the eyes. Hair is bright milk-tea ash brown. Thin see-through bangs, face-framing layers, and medium-long length reaching below the shoulders. The ends curl gently inward, with fine strands and natural stray hairs fluttering slightly in the summer air. Meticulous depiction of individual flow, soft gloss, and fine highlights. Clothing & Pose: A white fine-ribbed square-neck camisole, loosely draped with a translucent thin white shirt over the shoulders. Bottoms are pale sky-blue lightweight short pants with a white drawstring at the waist. A healthy, mature natural physique with a calm, feminine silhouette. The person holds a transparent cup at chest height with her left hand on the right side of the screen, while her right fingertips gently bring the straw close to her lips. A relaxed standing posture with hips shifted slightly to the left and a slight difference in shoulder height. Precise depiction of the contact between fingers, cup, and straw. Background & Light: A building rooftop in a Japanese urban area. Metal safety railings in the middle ground, and low-to-mid-rise buildings with thin power lines in the background, with no text or logos. The sky is a high-saturation clear blue, with small white cumulus clouds on the left and bottom. The transparent cup contains ice, fine carbonation bubbles, and pale light-blue ramune soda, with cold condensation depicted on the surface. The main light is a hard daylight coming from the upper left, brightly illuminating the cheeks, shoulders, arms, and top of the cup, while casting soft shadows under the chin and inside the shirt. Thin reflection of the blue sky added to the skin and white clothes. Composition & Camera: Vertical 2:3, low-angle shot looking up from a slightly low position. Natural perspective equivalent to 35-50mm. Precise focus on the person's face, with background buildings lightly blurred. Approximately 15% margin above the head, with hand-drawn white stars, notes, and short lines scattered on the left and right, and a white rough outline placed along the person's contour. Decorations create a bright and light rhythmic screen without obscuring the face, hands, or drink. Texture & Style: A bright and clean live-action photograph combining a summer fashion magazine and an SNS portrait. Realistic expression of natural skin texture, transparent carbonation, the transparency and fine wrinkles of the thin shirt, and the delicate movement of the hair. Refreshing color palette centered on blue, white, and pale light blue. Avoid excessive HDR or overly strong skin smoothing, adding light film grain and high-definition light depiction. Negative: Childish face, unnatural body proportions, excessive exposure, unnatural smile, extra fingers, missing fingers, fused fingers, fingers piercing through the cup, poor contact with the straw, distorted headphones, incorrect perspective, shadows contradicting the light source, garbled text, brand logos, watermarks, plastic-like skin.
