Naive Digital Selfie Avatar

Create a naive digital selfie avatar illustration of character_name 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 hair_color medium-length shaggy hair peeking out from under a hat_color 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.
