Nice realism to it, kinda funny too. I'm not sure why, but it almost seems complete with the background at least shaded in (though I have to say, the concept's pretty simplistic)... Anyway, it's fairly cool looking (you did a nice job bringing out the gradual shading too). There's a bit of unsymmetrical angle to the eyes (though I know how hard it is to get them almost perfectly straight, so it's fine), but what sorta bugs me is that it looks almost too dark, like it's in some wierd shade... But I still like it, so I'll give you a good score.
Oh, and I think KirtTheGreat's talking about some program you use on a Mac though (it's this photo filter that pretty much lets you blur out everything outside a small circle...). I get what he's saying, but then again it's sort of stupid to think you'd need to use it for reference (especially since it doesn't look the same).
