留有天空的海滩比基尼人像

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

主题：
留有天空的海滩

主体：
背对无云的蓝天与平静的大海，一位身着生成り白的比基尼上装和腰巾的年轻女性站在沙滩上。将人物置于画面中央的下半部分，头顶上方保留超过人物高度的广阔天空留白。从左下角延伸入画的木质步道，低低地横跨水平线。

人物·表情：
略微向画面右侧倾斜的小卵形脸庞，大大的棕色杏仁形眼眸正面对视前方。细眉轻轻弯成弧形，小巧笔直的鼻梁，轮廓清晰的玫瑰粉色嘴唇带着矜持的微笑。明亮的肤色，淡淡的眼线和脸颊柔和的红晕。及胸的棕发带有稀疏的束状刘海和长长的脸周发丝，轻柔的波浪在海风中向外散开。

服装·姿势：
生成り白的三角比基尼上装带有细肩带、环绕罩杯的小褶边，以及胸前中央的长系带。腰间斜缠同色系的薄布，在画面右侧的腰部穿过木质环固定，从那里向下延伸出深开衩的裙摆，露出前方的腿部。上半身略微向画面右侧扭转，画面左侧的臂膀自然下垂，画面右侧的手轻置于腰巾的系结附近。

背景·光线：
前景是残留足迹和细微凹凸的黄褐色沙滩，从左下角斜向延伸出竹绿色的板面步道。中景的蓝色海洋中点缀着小型游泳者和左岸的绿色浮标，水平线的右端有低矮的岛屿剪影。上部的大半为色调均匀的鲜艳蓝天。从上方倾泻的强烈夏日阳光明亮地照耀肌肤和白布，在沙地上投下短促柔和的影子。

构图·镜头：
纵向3:4。镜头从略低于人物胸部的高度几乎水平对准，收纳头顶的大片留白以及从头顶到大腿中段的中距离全景。人物位于中央下方，脸部靠近画面中央，水平线略高于肩部位置，天空占据画面上半部的绝大部分。将人物的脸部和上半身置于焦点，海面和岛屿则保留轮廓并轻微虚化。

质感·风格：
将蓝天、海水、沙滩和生成り白清晰分隔的高精细写实照片。真实描绘自然的肌理、细小的褶边和薄腰巾、沙上的足迹、木质步道、海面的细碎反射，以及风中散开的发丝。

负面提示：
不填充上半部广阔天空的留白；不大幅更改面部特征
