All that brush work paid off. I'm a 3d guys and I've always tried doing the effects in 3d and stayed away from doing them in ps, but when the results come out like what you've done here, then I think it's an awesome thing.
And I dont know why I got that way actually since I've been doing ps for about 5 years now and know it like the back of my hand and it was the first gfx app I used lol. I miss it the stuff I used to do in it. Well enough ranting. Great job bro.
