Streetwear Skater Pixel Avatar

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.
