In other words, you are laying down a challenge to OZ. They look good. Some are average but most are really good. I don't think you'll get OZ in a challenge. He's been slack lately. Try NDF, Legend Killer, Kaneanite and GP. They seem to be the better banner makers around here.
Couldn't you just post some of your old stuff, OZ? He just wants to see some of your graphics you've done. I don't think he cares if it's recent.
As for your work, Goatnce, all of them aren't too bad, but they aren't too good either. I didn't like alot of them, mostly because of the simple backgrounds/text. Alot of it seems kinda n00bish, but then again, if you ask GP, I can often be n00bish with my graphics too.
I did like the "Sick" one though. I agree that it is your best. Good work. <3
