Meh, have fun with the money. I hope you consider actually trying to make your own backgrounds next time around, its much more rewarding. Anyway, I'm too poor to afford your sigs :)
So did you make most of it in photoshop or 3ds max? I know photoshop cant really do 3d abstracts by itself, although there are combinations that mimick them. Nice job, the pic looks much better on deviantart
