Your sig is pretty simple. I like the text though. Kinda plain also. Your avatar try redoing it and sharpen a couple things on it.
I'm gonna start using renders and themes more when I'm better at Gfx.
I'll also be redoing my avatar today
I cant see anything wrong with it
its lookin good just dont change it ;p
For you're avatar don't try to add a lot of things.
It is an avatar...Avatars are meant to be simplistic.
If you have too many things added to it, it becomes crowded and looks ugly.
A simple image with maybe, some effects stemming around him you be more than good.
