More Rudi Rat sketches

Here are some more sketches as I try to come up with a look for Rudi Rat. I played around with the teeth a little as I try to get the whole image and idea of what a rat looks like down. But these images aren't going to work because he gives off a doofy look. Rudi Rat is more of a wise guy with a laid back personality. I'll keep working on it.
