LOL. I can imagine his voice yelling f u. 4/5 because of right hand for left hand

Not bad. Not too much here to really comment on. Obviously it's MSpaint and I think you did a pretty good job with it, but some improvements that should be made, aside from the obvious incorrect hand, is perhaps the thickness of the hand's lines. Since it'd be closer to the viewer, the lines should be thicker for more emphasis. That way it doesn't blend too much into what is behind it. That was really the main thing that kinda bugged me about this.

Other than that, not bad.

ummm.. his left hand is a right hand.
