way too sharp imo :/ the bg looks real hot, but i think less sharpening on the render would look nicer no text is fine, not always needed ^^
I actually like the look of it. I love messy/grungey sigs, its my style. I would just change one thing, have the render stick out a little more. Hes kind of hidden a little to much by the effects. Change that and I think it would be a cool tag dude.
it looks way better without text. but If I may say something, you can still have a nice grunge signature without it being too messy, there is just too much for you to look at all at once you know what I'm saying? Just a little too much going on. BUT I'm 100% sure if you took out some of the action around Ironman it would look so much better, but thats just my opinion. Keep at it try out some new things and keep improving!
