Create a naive digital selfie avatar illustration of {argument name="character name" default="a young person"} from the shoulders up, centered and facing the viewer with a simple direct smile. Use a square 1:1 canvas with a plain pastel sky-blue background. The character has {argument name="hair color" default="messy black"} medium-length shaggy hair peeking out from under a {argument name="hat color" default="green"} backward baseball cap with a small metal ring detail on the left side. Dress them in a blue denim collared zip shirt layered under a beige-and-brown checkered jacket. Render in a playful naive digital painting style with rough crayon-like texture, visible brush strokes, soft flat colors, simplified anatomy, minimal facial detail, warm peach skin tones, and an everyday casual selfie composition. Keep the crop close, with the head large in frame and the shoulders filling the lower third. Avoid photorealism, hard outlines, text, logos, or complex background details. 创作一张 {argument name="character name" default="年轻人"} 的天真风格数字自拍头像插画，构图为肩部以上，居中且面向镜头，带着简单直接的微笑。使用 1:1 的方形画布，背景为纯净的淡天蓝色。角色留着 {argument name="hair color" default="凌乱的黑色"} 中长蓬松乱发，从 {argument name="hat color" default="绿色"} 反戴棒球帽下露出，左侧带有小金属环细节。身穿蓝色牛仔翻领拉链衬衫，外搭一件米棕色格纹夹克。采用俏皮的天真数字绘画风格渲染，具有粗糙的蜡笔质感、可见的笔触、柔和的平涂色彩、简化的解剖结构、极简的面部细节、温暖的桃色肤色以及日常休闲的自拍构图。保持近景裁剪，头部在画面中占比大，肩膀填满下三分之一区域。避免照片级真实感、硬轮廓线、文字、标志或复杂的背景细节。
