Firstly yes it should be allowed in the gallery because it's good quality. And plus we can't really see his face so it's doesn't really matter all that much ;)
I have nothing really much to say cept for good colours and good use of text- The only things that bother me are the pixels on the text and the blurriness (because the vector's so sharp~~) A stronger shadow (hard edged) may have also helped... but overall, hell yeah, this is funky! (I'd also move the welcome to your mind a bit closer to the centre... it's a bit close to the edge atm ;))
Great work!
