Natural Beach Sunset Portrait

A young adult East Asian woman kneeling on a {argument name="setting" default="light beige towel spread on a beach"}, shot from above the head to near the calves. The subject is centered slightly to the right, body turned slightly to the left, kneeling with knees bent, one leg extended forward and the other tucked under; upper body leaning forward naturally, arms straight, hands supporting her on the towel. She looks directly at the camera with a quiet, soft, slightly lazy gaze, lips naturally parted, no obvious smile. She has a delicate oval face, almond deep brown eyes, natural thin brows, a slender nose bridge, and light nude-pink lips. Extremely light makeup, only natural lashes, fine eyeliner, soft blush, and moist lip color. Skin is fair and warm-toned, retaining real pores, fine vellus hair, slight skin tone variations, natural sweat, and sunlight highlights, no plastic skin smoothing. Long dark brown hair flowing naturally with a slight damp look and soft waves; light wispy bangs in front, some hair strands blown by the sea breeze across cheeks, shoulders, and chest, hair edges illuminated by the sunset. She wears a {argument name="attire" default="light sand, nude beige thin-strap triangle bikini"}, matte soft fabric, simple cut, color close to skin tone but with clear edges, natural fit, opaque. Some sand and moisture on the swimwear and skin. Background is a quiet beach, with light blue-green sea and gentle waves in the back left, dark islands or mountains in the distance, and a blurred coastline in the back right. The sun is at a low angle in the back right, creating warm golden side-backlighting, hair rim lighting, and highlights on shoulders, neck, and arms, with bright sparkling spots on the sea. Sky is a gradient of light gray-blue and cream gold, overall low saturation, low contrast, warm and transparent. Photography style: 85mm portrait lens, f/1.8, close-up shot slightly below eye level, shallow depth of field, clear eyes, soft sea blur, real textures of sand, towel, skin, and swimwear, slight ISO 200 film grain, soft highlight bloom, a mix of Japanese portraiture and high-end lifestyle photography, photorealistic. Avoid: underage features, nudity, exposure, transparent swimwear, erotic poses, CG, anime, excessive skin smoothing, exaggerated body proportions, incorrect fingers, deformed legs/feet, stiff poses, strong HDR, over-sharpening, cluttered tourists, text, watermarks, logos.

一位年轻成年东亚女性跪坐在{argument name="场景" default="海边沙滩铺开的浅米色毛巾"}上，画面从头顶拍至小腿附近。人物位于中央偏右，身体略微侧向画面左侧，双膝弯曲跪坐，一条腿向侧前方展开，另一条腿收在身体下方；上半身自然前倾，双臂伸直，双手撑在毛巾上。她正面看向镜头，眼神安静、柔和、略带慵懒感，嘴唇自然微启，没有明显笑容。

她有精致柔和的鹅蛋脸、杏仁形深棕眼睛、自然细眉、纤细鼻梁和浅裸粉色嘴唇。妆容极淡，仅保留自然睫毛、细眼线、柔和腮红和湿润唇色。皮肤白皙偏暖，保留真实毛孔、细小绒毛、轻微肤色变化、自然汗感和阳光高光，禁止塑料磨皮。

深棕黑色长发自然披散，带轻微湿润感和柔软波浪；额前有轻薄碎刘海，部分发丝被海风吹过脸颊、肩膀和胸前，发丝边缘被夕阳照亮。

她穿{argument name="服装" default="浅沙色、裸米色细肩带三角比基尼"}，布料哑光柔软，剪裁简洁，颜色接近肤色但边缘清晰，贴合自然，不透明。泳装和皮肤上带少量细沙与水汽。

背景是安静海滩，左后方为浅蓝绿色海水与轻柔浪花，远处有深色岛屿或山体，右后方为模糊海岸线。太阳位于画面右后方低角度，形成暖金色侧逆光、发丝轮廓光、肩颈和手臂高光，海面出现明亮闪烁光斑。天空为浅灰蓝与奶油金渐变，整体低饱和、低对比、温暖通透。

摄影风格：85mm人像镜头，f/1.8，略低于眼睛的近距离拍摄，浅景深，眼睛清晰，海面柔和虚化，真实沙粒、毛巾、皮肤和泳装纹理，轻微ISO 200胶片颗粒，柔和高光晕染，日系写真与高级生活方式摄影结合，photorealistic。
