Heh, Looks pretty tight. I like the work you've been doing with wireframes. Ok, Colors are pretty hawt, but I don't liike the lonely light blue part on the left. The focul's wonderful. really kickin'. Nice light as well. ^_^ My only advice would be, Slightly sharpen a few areas closer to him. Not too sharp, just a tiny bit. Then, take that blue and change it's hue! ... That ryhmes lol. *dorkeh look* Nice.
Love that sig. Only thing is I dont like the render. Otherwise, very nice effects and I love the wireframes. Those are really hard to work with.
