I'm loving that background and the border in the first sig. But the render and the text both kinda blow; especially the text. It just doesn't fit. Try finding a grunge font and messing around the the blending layers, like Soft Light or something.
Man you stole the words right out of my....well brain cuz I don't talk while I type But ya, that BG is very cool, the render in my opnion is ok, but could be better. The text does blow though But a very nice BG, i'll look forward to some good graphics!
Nice dude, overall, i'd say 7.5/10 the reason that is, is because the render is sooooo close, you have to stare at it for a little while before you can make out what it is.. It's a dude wearing a gas mask, right?
