Portrait Gribouillage Style Paint

A crude, childlike digital doodle portrait on a plain [light gray] background, centered and cropped from the chest up. The subject is a goofy adult man with a scruffy [light blond] beard and messy [dark] hair mostly covered by a ribbed [gray knit beanie]. Pinned on the right side of the beanie is a small [orange circular badge] with the white text "[10]" inside. He wears oversized thick-framed [black sunglasses] completely concealing his eyes. An exaggerated, massive toothy grin with large uneven square white teeth occupies most of the lower half of his face, showing tiny red marks along the gumline. A simple, clumsy cartoon nose sits above the mouth, and one prominent ear protrudes on the left. He is dressed in a bulky [black jacket] worn over an [off-white sweater]. The artistic style features intentionally sloppy, amateur drawing quality with jagged black outlines, scribbly fills, flat shading, naive proportions, and the distinct look of an MS Paint or rudimentary tablet sketch.
