The Adversary

Ah, another Isaac fanart! Today, here's one of the most annoying and damn bosses in game, the Adversary! 
I decided to draw him realistic, since there was already a couple of Isaac's characters which are drawn in that chibish Isaac style. 
Personally I think it came out ... awesome *.*
And, at last, wings are not one piece of crap, like the ones I've drawn before!  
Hope you like it!
