Wow, I think this is cool because you can figure out what it is all of the characters do or rather, what they don't do. It's obvious the guy on the left hand side can't see. I'm guessing the guy with no arms can't touch? I was thinking he also couldn't taste because of how his mouth was bandaged. I think the Asian has headphones on, so he can't hear. I would have liked to see this turn into a real project.
It's too bad you put it in a blank background. The previous picture was better because it had one. All of these characters seem to be quite unique. I imagine the short one is modeled after Krillin. Of course, I think that's actually just a generic appearance many Buddhists take on.
