Eh, it's decent, nothing too great. Love the text though, got a link to where you downloaded it? Anyways, there's way to much nothing in the middle of the sig, either get a bigger render, center the render, or make the sig smaller overall. Besides that, try to blend Zexion a little more into the background. Not bad.
Thanks fr the comments. Here's a link to the text I used. It's called Visitor. http://www.dafont.com/search.php?psize=m&q=visitor
