I'm going forward with this character for a new kids' non-fiction idea I'm putting together. It pretty much came together with no fuss at all, so I'm taking that as a good omen.
While I was doing this color version of the design below, I suddenly realized that the sleeves were completely incompatible with movement or normal wear, and were completely different from one another. If this were animated, I thought of a number of ways the penciled design might work, but since it's a one-off color concept design, I decided to redesign it a little. I can't believe I never noticed it in the original pencil!
