Very nice!
I like the trippy font. It's also a very human expression, but pretty slate on expressing his comedic personality.
The shading all around looks good, I like the gradient applied to the tasteful background. The sweatshirt is shaded to look realistic, and the shadows around his neck look right.
It only seems a little too dark near the top, and one detail I wanted to point out is it appears that the mustache seems to be on top or in front of the tip of his nose. Possibly it's an optical illusion, but it's merely what I perceive.
Still, all around this looks great! Has James Fritz seen this? I think he would be flattered :)
Good job! Voted 5
