Bluerob: As stated before, your Tank is phenomenal! I have no idea what cons I'll be attending in the upcoming future, though. Maybe Megacon?
Flay D: I'd ask some of the people that have already done a Smoker about pointers with the tongue. It would be awesome if you found a way to make it look all glossy and slimy.
KnuxieChan:Perhaps you can use something like http://www.funfancydress.com/witch-gloves-3d.html
as a base and go from there?
Mastrpuppet: Have you tried inquiring in the make-up thread? I'm almost sure you can come across some make-up hints for zombie flesh!
