Bad MS Paint Meme Portrait

A childlike, crudely drawn digital portrait against a pure light gray background, centered close-up of the upper body. The figure is a comical adult man with messy light blonde stubble, most of his dark hair hidden by a gray ribbed knit hat. A small orange circular badge with the white number "10" is pinned to the right side of the hat. He wears oversized, thick-rimmed black sunglasses that completely obscure his eyes. His face displays an exaggerated, toothy grin, with oversized, square white teeth dominating the lower half of his face, drawn clumsily and unevenly, with a few tiny red marks on his gums. His nose is simple and cartoonish, and his left ear protrudes. He wears a thick black jacket over a cream or off-white sweater. The style deliberately strives for a messy, amateurish, childlike doodle feel: jagged black outlines, rough lines, disproportionate proportions, childish anatomy, minimal shading, and random fill colors, giving the impression of a hand-drawn MS Paint or cheap tablet sketch. Keep the composition simple and humorous, with a charming "ugly-cute" feel, like a poorly drawn viral meme avatar.
