Beach bikini portrait with vast blue sky

Theme:
Beach with Sky Space

Subject:
Against a cloudless blue sky and a calm sea, a young woman dressed in an off-white bikini top and a waist wrap stands on a beach. Position the character in the lower half of the frame, leaving a vast sky space above the head that exceeds the character's height. A wooden boardwalk extending from the bottom left corner crosses the horizon at a low level.

Character · Expression:
A slightly oval face tilted towards the right side of the frame, with large brown almond-shaped eyes looking directly ahead. Thin eyebrows gently curved into an arch, a small straight bridge of the nose, and well-defined rose pink lips with a reserved smile. Bright skin tone, faint eyeliner, and a soft blush on the cheeks. Chest-length brown hair with sparse wispy bangs and long strands around the face, soft waves spreading outwards in the sea breeze.

Clothing · Pose:
An off-white triangle bikini top with thin straps, small frills around the cups, and a long tie at the center of the chest. A thin fabric of the same color is wrapped diagonally around the waist, secured through a wooden ring at the waist on the right side of the frame, from which a deep-slit skirt extends downwards, revealing the legs in front. The upper body is slightly twisted towards the right side of the frame, the arm on the left side hangs naturally, and the hand on the right side is lightly placed near the knot of the waist wrap.

Background · Lighting:
The foreground is a yellowish-brown beach with lingering footprints and subtle irregularities, with a bamboo-green plank boardwalk extending diagonally from the bottom left corner. In the middle ground, the blue ocean is dotted with small swimmers and a green buoy on the left bank, with a low island silhouette at the right end of the horizon. The majority of the upper part is a bright blue sky with a uniform tone. Intense summer sunlight pouring from above brightly illuminates the skin and white cloth, casting short, soft shadows on the sand.

Composition · Lens:
Vertical 3:4. The lens is aimed almost horizontally from a height slightly lower than the character's chest, capturing a large area of white space above the head and a mid-range full view from the top of the head to the mid-thigh. The character is located in the lower center, the face is near the center of the frame, the horizon is slightly above the shoulder level, and the sky occupies the vast majority of the upper half of the frame. The character's face and upper body are in focus, while the sea surface and islands retain their outlines and are slightly blurred.

Texture · Style:
A high-definition realistic photograph with clear separation between the blue sky, sea water, beach, and off-white. Realistically depicts natural skin texture, small frills and thin waist wrap, footprints on the sand, the wooden boardwalk, fine reflections on the sea surface, and hair strands spreading in the wind.

Negative Prompt:
Do not fill the vast sky space in the upper half; do not significantly change facial features
