Vertical 9:16 photo-style portrait. An adult woman stands slightly to the left of the center at the seaside near a harbor at dusk. The subject is framed from the upper thighs to above the head, occupying approximately 70% of the lower part of the frame. The upper half leaves ample space for a pale purple and pink sky, with the ships and sea in the background softly blurred. Subject/Expression: A natural and realistic adult woman. She has refined Japanese-style features, with long black hair slightly tousled by the sea breeze. Her gaze is directed at the camera, lips slightly parted, with a calm and lingering expression. Evening light hits her face, neck, shoulders, and arms quite strongly, making only her skin appear slightly brightly exposed. Clothing/Pose: A pale lavender and orange floral bikini. The top features a ribbon tie, and the bottom has side ribbons, a design that balances cuteness and maturity. Her right arm is raised above her head, with her fingertips touching her hair. Her left arm hangs naturally at her side, and her hips are slightly tilted. Her weight is shifted to one leg, in a portrait pose as if taken naturally at the seaside. Background/Light: A quiet harbor seaside. Several small fishing boats and pleasure boats are lined up in the background, with the sunset colors reflecting on the water's surface. Small waves wash onto the sandy beach, and distant harbor lights are softly blurred. The sky is a gradient of lavender, pink, and pale orange. Soft evening light enters from the upper left, casting slightly strong highlights on the subject's face and upper body, with thin purple shadows on the opposite side of her body. Composition/Camera: Medium telephoto lens portrait. The camera is positioned slightly lower than chest height, at a slight upward angle. The focus is on the subject, with the background ships and waves blurred by a shallow depth of field. Ample sky space is left above the subject's head, and the shoreline and sandy beach are included at the bottom. The harbor, sea, and sky are divided into foreground, middle ground, and background, creating a natural sense of depth. Texture/Style: Realistic photographic expression. Soft skin texture, slightly blown-out highlights, and a pale film-like color tone. Low contrast, with a transparent finish that makes the most of the pink-purple sunset scene. Avoid excessive processing, aiming for a seaside portrait taken with natural light. Negative: Unnatural face, unnatural gaze, extra fingers, missing fingers, fused limbs, broken joints, poor contact between hair and hands, unnatural gravity, incorrect perspective, shadows inconsistent with light sources, excessive blown-out highlights, plastic-like skin, garbled text, logos, watermarks.
