It kinda ''old style'' pop up. I can't undestand the connetion between the thing above the sig. The text isn't good. blending it will solve the problem. I do like the backround thought.
This could rather be some banner for a game or something but not a signature I guess. I do not like that "box" signatures but that is just about me. The signature could need a better text, it is awful, and a better lighting, I think dopefromhell said it all.
I don't like how the sig kind of cuts off around his neck and doesn't blend with anything. You should spice the sig up with some smudging and colors. Try some gradient maps or photo filters. ~T9
