I might be interested, too, but it will depend on how you exactly want this to work out. I can only do animals because 3d human models require way too much time and patience to make and I won't have any of that, haha. So, randomly assigned characters might would mean I can't participate.
I really like the characters by @Awesomeness_Studios though, It would be fun to work with them.
And if it's okay to join with a not-yet published comic (called Burned Out Candle), I can offer my grumpy pumpkin-headed cat named Pumpkin (very creative) and my cute and fluffy monster Sludge. I post some pictures of them as soon as I can get them into a better shape.
