I think the major flaws are the hands, especially the fingers pointing to the also ugly feet. The position of the feet make it look like the guy's hanging somehow. Or maybe he's balancing on a invisible ball?
But I sort of like the surreal look and the different sized buttons.
Looks rather like the surreal version of a homosexual pedophile psycho (the) rapist (hehe) and for those who know me, that's whom I'd prefer to serve my coffee.
