The graphic is pretty cool, but I don't think the text suits it.. the innerglow colour is wrong for the background, and the text is too smooth for a rough background like that.. also the small text is very hard to read.. I think with a better font, bigger text (to fill in the left half a bit more) .. and readable small text underneath it'd be perfect
I think i like your current sig better i must say. Although, its a pretty good attempt. Maybe if you put something behind the text it could help.... like..... a translucent type black box in the background... that would make the text stand out a bit more.
