Designs for a fake video game about violent toons

For Media Studies (I'm going to be attending college at last this year), I was among a few people asked to develop a video game idea, and draw some designs. What I gave to the teacher greatly impressed him. The game I thought up was named after that embarrassing fanfic of mine, Toontown Beatdown, so here are some rough (let me repeat that, rough) sketches of the exclusive/parody characters I thought up. Who knows? I might even use them in later pictures.
