Summer Seaside Bubble Portrait

Subject: {argument name="subject" default="Summer Bubble Seaside"}\n\nPerson/Expression:\nA {argument name="person" default="woman in her 20s"}. Natural and mature Japanese facial features with transparent photographic makeup. The skin is bright and smooth, with a realistic texture that slightly leaves pores and fine hairs. Pale rose blush, thin natural lashes, soft brown brows, and coral pink lips. The expression is calm and slightly dreamy, with the lips slightly open and the gaze directed slightly above the camera. The hair is dark brown medium length with light see-through bangs, and the ends and bangs sway naturally in the sea breeze.\n\nClothing/Pose:\n{argument name="outfit" default="Pale ice blue sleeveless rib knit and a white light cotton long skirt"}. A clean summer seaside look. The person sits sideways on a low concrete wall along the sea, twisting the upper body slightly toward the camera. The person's right hand lightly presses the hair at the side of the ear, and the left hand supports the body on the wall. One knee is raised, and the other leg flows naturally to the right of the screen. The skirt catches the wind around the knees, creating fabric overlaps and contact shadows.\n\nBackground/Light:\nAlong the coast of Shonan or Kamakura. Sea surface at the bottom, with blurred low mountains and coastal cityscapes in the distance. Most of the screen is a clear cyan-blue sky. Large and small bubbles float around the person and in the sky, creating iridescent reflections and soft bokeh. Sunlight enters strongly from the upper left of the screen, creating bright highlights on the hair contours, cheeks, shoulders, arms, and the top of the skirt. Shadows fall shallowly toward the lower right of the screen, gently lifting the skin with reflected light from the sea.\n\nComposition/Camera:\nVertical 2:3. Low-angle medium-view portrait. The person is placed from the lower half to the center of the screen, with the face slightly above the center. Leave a large margin for the sky and create depth with bubbles. The camera looks up slightly from a position lower than the seating surface. A natural low angle that is not too wide-angled, so legs and hands do not expand unnaturally. The focus is on the eyes, and the background sea and distance are softly blurred. Some bubbles in the foreground are largely and faintly blurred.\n\nTexture/Style:\nHigh-quality Japanese photography. A transparent Japanese-style portrait photo rather than a summer magazine gravure. Do not make primary colors too strong; the blue sky is more cyan, the skin is bright and natural, and the white skirt is not overexposed. The light is dazzling but not too hard, adding fine particles and faint halation like a film photograph. Carefully depict the iridescent reflections of the bubbles, fabric wrinkles, fine strands of hair, and natural shadows on the skin.\n\nNegative: Face that looks like a minor, infantilization, excessive skin correction, plastic-like skin, cheap influencer style, excessive exposure, see-through clothes, exposure of underwear, exposure of points, unnatural faces or gazes, extra or missing fingers, fusion of limbs, breakdown of joints, collapse of leg perspective, floating body, poor contact between clothes and body, shadows inconsistent with the light source, unnatural deformation of bubbles, characters, logos, watermarks, excessive HDR, excessive sharpness, obvious AI feel.
