The best cartoons, cartoon logos, and cartoon advertisements are complicated but don't appear complicated. The cartoon on the left is from the Basketball Department of my internet store. It has much more than shape and color. It has shadow on the face, arms, and clothing created by multilayer shading. It has spot reflection on the arm and head from overlays. And it has gradient reflection on the basketball created by a different software entirely. Simple it seems, but simple it's not.
I'm always striving to make my cartoons, cartoon logos, and cartoon advertisements better. When your name is on the line, why settle for less than the best?
