夏日天空下的动漫少女

创作一张高清、简洁的动漫插画，描绘一位少女站在户外明亮的夏日天空下。采用低角度后方视角，她转头回望观众。她留着 {argument name="hair color" default="深棕色"} 的头发，扎成高侧马尾，系着 {argument name="hair ribbon color" default="藏青色"} 的发带，留有长长的碎刘海，拥有一双柔和的紫褐色大眼睛、小巧自然的嘴唇和微红的脸颊。她穿着一件超大号的纯色 {argument name="shirt color" default="白色"} 短袖 T 恤，衣服松垮地垂在身上，长度过臀，带有细腻的褶皱和阴影，内搭深色运动短裤。她的姿态随意而略显羞涩，一只手轻触 T 恤下摆或口袋区域，身体背对镜头，脸部回望。背景为明亮的蓝天，点缀着蓬松的积云，光线充足，采用清晰的赛璐璐动漫渲染风格，色彩过渡柔和，线条细腻，营造出治愈的日常番氛围。构图：1:1 正方形画布，角色居中并占据画面主体，低机位视角强调天空，无文字，无水印，无多余角色。

Create a clean high-resolution anime illustration of a teenage girl standing outdoors under a vivid summer sky, viewed from a low angle behind her as she turns her head over her shoulder to look at the viewer. She has {argument name="hair color" default="dark brown"} hair in a high side ponytail tied with a {argument name="hair ribbon color" default="navy blue"} ribbon, long loose bangs, large soft purple-brown eyes, a small neutral mouth, and lightly blushing cheeks. She wears an oversized plain {argument name="shirt color" default="white"} short-sleeve T-shirt that drapes loosely over her body and reaches past the hips, with subtle folds and shaded fabric, plus short dark athletic shorts visible underneath. Her posture is casual and slightly shy, one hand tucked near the shirt hem or pocket area, shoulders turned away while her face looks back. Use a bright blue sky background with scattered fluffy white cumulus clouds, strong daylight, crisp cel-shaded anime rendering, soft gradients, delicate line art, and a wholesome slice-of-life mood. Composition: square 1:1 canvas, character centered and occupying most of the frame, low camera angle emphasizing sky, no text, no watermark, no extra characters.
