Cool drawing. I like the abstract firey background look on this piece. I was the supervising prop model and FX designer for the first few seasons of that show. It was one of my favorite shows I ever worked on, so this takes me back a little.
I got in as a clean-up artist by sending in a portfolio. Tightening up storyboards and essentially "Cleaning" them up. I was then moved up to storyboarding and then to a director. It is a pretty stressful job at times but come on, I'm working in cartoons for my career, how can you not love your job.
