What is your opinion for this?

I'm really liking it, but the signature (if you use it with toribash forums) will have to be 450x100, and the avvy is just a 100x100 section of the sig...

But other than that i see alot, although the background doesn't seem to fit to much.

Waaaay too oversharpened.
Also, I don't like the font on the avatar, just doesn't fit in.

Try to place the render not directly in the middle and place the font closer to the render.
