Summer Rooftop Portrait in Blue-and-White School Uniform

Generate a Japanese-style youthful cinematic portrait of a real-life character cosplayer. The subject is a clearly adult female cosplayer. Preserve the most recognizable hairstyle, hair color and signature accessories of the chosen anime or game character. She wears a neat, complete white short-sleeved school uniform top with royal-blue collar and cuffs, paired with a pleated skirt.

The subject leans against the grey metal railing of an open rooftop, one hand gently cradling her cheek and the other resting naturally on the railing. Her expression is quiet and relaxed, and she smiles at the camera. Use a slightly low camera angle in a medium close-up vertical composition, with the subject placed slightly below center, the railing crossing the foreground diagonally, and a large expanse of clear blue sky as negative space.

Bright summer natural light; the white clothing and blue sky form a crisp blue-and-white palette. Skin is soft and luminous, and the hair is gently stirred by a breeze. The image has fine film grain, soft highlights and a slightly faded, nostalgic feel. Overall it should look like an accidentally captured still from a campus summer film: fresh, quiet and natural. Single person, single image, no collage, no added text.

生成一张日系青春电影感的真人角色 Cos 肖像。人物为明确成年的女性 Cosplayer，保留所选动漫或游戏角色最具辨识度的发型、发色与标志性饰品；穿整洁完整的白色短袖校服上衣，搭配宝蓝色领口、袖口与百褶裙。

人物倚靠开阔天台的灰色金属栏杆，一只手轻托脸颊，另一只手自然搭在栏杆上，神情安静放松，微笑看向镜头。采用略低机位的中近景竖幅构图，让人物位于画面中央偏下，栏杆斜向穿过前景，大面积晴朗蓝天作为留白背景。

明亮的夏日自然光，白衣与蓝天形成清爽的蓝白配色；肤色柔和通透，头发被微风轻轻吹动，画面带细腻胶片颗粒、柔和高光和轻微泛白的怀旧感。整体像偶然定格的校园夏日电影剧照，清新、安静、自然；单人、单幅画面，不拼贴、不加文字。
