Oh hey I remember your avatar, back from when I went to MFGG. Welcome to pixeljoint, my friend :) (I think my username was Mike when I finally left.)
As for the image, the only thing I don't like is that fact that all of the green/black squares have AA on their corners, but the blue squares/eyes don't. Other than that I would say this is a-okay!
I was certain that I had put AA on those corners, too, but apparently not. I'll go and fix that.
