The BG is very nice, although I think you went a bit overboard with the dots. I like the diagnol stripes though, they look cool, maybe a badge or something else could be faded in the BG to fill it in more.
The render looks good, as well as the effects you've used. You could maybe add some blur around him or something to help reflect the lighting ?
The colour scheme looks good, the nice suttle red fading out. I also like the text alot.
Overall a nice sig, and I await your battle eagerly. Well done.
