街头滑板像素头像

一位少年滑板手的48x48像素艺术头像，反戴红色帽子，脖子上挂着耳机，穿紫色连帽衫，肩后露出一小块滑板。复古16位调色板，温暖肤色，品红连帽衫阴影，粗大像素，细腻的轮廓抖动，灰色砖墙背景带一个小小的喷漆涂鸦，方形居中，酷炫放松的都市氛围。

A 48x48 pixel-art avatar of a teenage skater with a backwards red cap, headphones around the neck, and a purple hoodie. A small skateboard peeks over one shoulder. Retro 16-bit palette with warm skin tones, magenta hoodie shading, chunky pixels, subtle outline dithering, gray brick-wall background with a tiny spray-paint tag, centered square, cool relaxed urban vibe.
