I can definately fix that avatar as well as making your sig a normal size. I never saw that pic before, thanks for posting the larger one.
As far as the others, I have seen them before. The 'Paw-and-maul-you' was kind of my inspiration for this wallpaper I made (its still incomplete, but I got tired of working on it). Don't let those ****sticks at steelersfever fool you, they claim it's "theirs" and made by someone on their site. Long story, lol.. but back on topic.. I'll have your avy and sig done sometime tonight.
Don't forget to check out the other downloadables offered by steeleraddicts.
