This is just a basic Pokemon-style sprite that I toyed around with a bit in anticipation of a game I'm going to make soon, but I seem to have messed up the models' spacing. I'm somewhat new to this, so I would greatly appreciate it if someone could help me out.
When I tested this guy out, a couple of his models (not sure what the proper term is) are too close together, so a little piece of a hand from the adjacent model shows up when he walks. I've been messing with the spacing, and I just can't figure out how the game determines the parameters for each model's cutoff (so that they don't all run together), since character sprites can be various sizes. If someone could correct this error for me or tell me what I need to do to fix it, I'd be very grateful!

Thanks!
