I can't find anything wrong with your sig, but for some reason, it just doesn't appeal to me. It's well done and all, just... plain. But still, 8/10. And a 9/10 for your sig :thumbsup:
I'll be changing my sig soon, so be as harsh as you want! Might even make a pixel sig, if I can be bothered...
something good about a sig is that
there should be a focal point, light source, depth, good choice of colors, good placement and style of text, a good use of c4d, and a good flow
