I've been cartooning my whole life, using various media. I'm familiar with both vector- and raster-based computer illustration.
My signature cartoons are expressive, rodent-like critters I call "underlings™." The animated GIF at the bottom of my home page contains an underling, and I have a Gallery of Underlings! containing sketchy scans from a complex business card/booklet I designed for Sue Barry and Associates years ago. I also have an underling drawing and merchandise business called Underlings!™, which I launched in early 2004 (go ahead and click on the link--you may find something you like!).
