Awesome Picture
I like the idea of those big deformed heads that could also be used as arms just like the gluttony monsters in the game Dantes Inferno, reminds me of a Picture i just sprayed some weeks ago even though mine isnt nearly as detailed...time limit you know..
what i would suggest is that some of the background heads needs more detail especially compared to the one at the very top. But i still think that this monster is because of its unproportional design, just like taken from a kids imagination.
Keep up the good work.
