Get rid of that dot pattern and I think you should get a new bg. The background is way too random. It makes it seem like the background and the render are paper thin and theyre just sitting on top of each other. The other thing is, I'm not a big fan of those blurry patches, they dont look good. It looks like shadow there is hanging onto something, except in your sig, he's not. So it looks a bit awkward. I'm going to hate myself for saying this because theyre disgusting, but itd make a good popout sig if youre into that. If you had him swinging out, holding onto something in the sig or on the border or something. Dont do that though, popouts are gross The typography could use some work (who's couldnt right? lol). The whole slanted idea seems like it would be good, but it doesn't work well. At least not in this case. I also think you have too much text. Pick whats necessary (i.e. is "climb-x" needed being that your posting it on cx?). Also, is "keep up" a requisite? This sig is representing you, so aside from your name, the rest can be left out. That's just the way I see it.
