Character design final project

It's a relief to be done with everything for the semester! I'm probably going to be taking a break for a little while, so until then I'll trickle a new image from my final project every couple of days.
The assignment was to take one of our characters from earlier in the semester and design three other characters to go with it---so that in the end we would have a hero, a love interest, a comic sidekick, and a villain---all done in the same style. Then we had to do two environments from their world.

So here's the character I picked to design around, fitting him into the role of comic sidekick:
















And here's his buddy, the hero. I'll post the others later, so check back soon!
