A woman is sitting sideways with her legs bent on a light ivory towel spread on a sunny sandy beach. The figure largely occupies the right side of the screen from the center, in a vertical composition with depth extending from her feet to her face. Her body is facing the sea, but only her upper body and face are turned back towards the camera. Figure/Expression: Bright, beige-toned skin with natural flush. Long dark brown hair, with light bangs and wisps around the face, the ends slightly swaying in the sea breeze. Delicate brown-toned eye makeup, faint coral pink on the cheeks, and sheer pink-beige lips. Chin slightly tucked, a calm and composed gaze directed at the lens, and a natural expression with lips slightly parted. Clothing/Pose: A simple sand-beige bikini with a matte finish. A design where thin straps and a small knot at the waist appear natural. Both knees are bent, with legs flowing from the back towards the foreground of the screen, one leg lightly overlapping the other. Her waist remains sideways, her upper body slightly raised, and her own right hand is placed on the towel to support her weight. Her left arm is kept close to her body. Ensure natural grounding and center of gravity for fingertips, elbows, knees, and ankles, and add fine wrinkles to the towel conforming to the pressure from her limbs. Background/Light: In the foreground, bare feet with sand grains and a finely woven towel. In the midground, a bright sandy beach and white wave crests; in the background, a clear blue sea; in the far left of the frame, a small tree-covered cape and a white-walled building. The sky is a clear light blue with few clouds. Warm morning sunlight streams in from the upper right of the screen, creating soft highlights on the contours of her shoulders, arms, waist, and legs. Shadows fall to the lower left, and faint reflected light from the sand and towel complements the skin's shading. Scatter fine light reflections on the water surface. Composition/Camera: 9:16 vertical orientation. A close-up, low-angle photograph capturing the full body of the figure. The camera shoots from a low position near the edge of the towel, making the front foot slightly larger and placing the face around the upper third of the screen. The figure occupies about two-thirds of the screen, leaving a wide expanse of blue sky at the top. Natural compression similar to an 85mm portrait lens. Focus on the eyes and face, smoothly blurring the coastline and cape. Texture/Style: High-definition photographic rendering. Skin is not overly uniform, retaining fine texture, sand grains, peach fuzz, and natural sheen. Carefully depict individual strands of hair, dry hair bundles (not wet), towel fibers, sand particles, and wave reflections. A bright, transparent resort portrait contrasting warm skin tones with a vivid blue sea. Natural color tones, shallow depth of field, subtle film grain. Negative: Person appearing underage, unnatural face, unnatural gaze, excessive body deformation, extra limbs, extra fingers, missing fingers, fused limbs, broken joints, confusion of left and right legs, floating body, poor contact with towel, incorrect perspective, shadows inconsistent with light source, excessive skin smoothing, plastic-like skin, text, logo, watermark.
