The Jim Henson Co. recently debuted a new show on PBS called "Sid the Science Kid"
I was asked by Brandolution, the company that is doing the licensing for the show to come up with some character art for their style guide that would reflect the look of the show and yet still be vectorized as this is more desirable for product than Photoshop bitmap files.
After boning up on the gradient mesh tool in Adobe Illustrator, (oy!) this is a little peak of how it came out. It was a challenge, but I got the hang of it after awhile.
