So, I pitched this for a position as a concept artist for an educational video games. Didn't have much time to make them as finished as I would have liked to, but oh well. Here's a character sheet of sorts, a customization screen and a gameplay screen.
It ended up not being picked, but I quite like these little guys now. I decided to call them kwimbles - I don't know why, I just randomly thought of the name and will probably regret it in the morning, but that's how you know you're living in the fast lane.
