A photorealistic natural beach selfie of a fictional 20-year-old adult Japanese woman, clearly adult appearance, Japanese idol-like cute face, soft medium-to-long brown hair, slightly windblown hair, playful relaxed smile, natural facial asymmetry, realistic pores, slight skin imperfections, natural skin texture, not overly symmetrical, not plastic skin.
Recreate the pose and camera angle without using any reference image: an extreme low-angle wide-angle selfie from below, as if the camera is held near chest or waist level and pointed upward. The woman is leaning forward over the camera, looking directly down into the lens with a confident playful expression. Both arms extend toward the camera from the left and right edges, creating strong perspective distortion. Her face appears near the upper center of the frame, her upper body is close to the lens, and her torso extends downward toward the bottom of the image. The composition is dynamic, intimate, and slightly exaggerated by the wide-angle smartphone lens.
She is wearing a tasteful black frilled bikini with a bandeau-style top and matching side-tie bikini bottoms. Clean swimsuit gravure style, healthy summer beach mood, tasteful and refreshing, not vulgar. Large natural bust, soft natural fullness, natural gravity, natural roundness, natural cleavage formed by the swimsuit structure and leaning-forward posture, realistic bikini fabric tension, no exaggerated compression, no balloon-like shape. Smooth sunlit wet skin with realistic texture, small water droplets on shoulders, chest, stomach, and arms.
Bright blue sky behind her, turquoise ocean and sandy beach in the background, strong summer sunlight, glossy highlights on wet skin, shallow depth of field, realistic smartphone selfie feeling, high-resolution photorealistic natural photo, clean magazine gravure, natural body proportions, realistic hands and arms, no anime style, no illustration style.
