James, I think what people are trying to say and you don't accept is that the rules of physics do not and don't have to apply in cartoons. You only have to watch Tom and Jerry to appreciate the validity of that. The pussy cat drawn by the OP is a cartoon. In a cartoon you can have a thousand different light sources, real or imagined. Just because some cartoonists adhere to the rules of lighting, it doesn't make it a crime to ignore them. I don't have a problem with the OP's cartoon. If it was a still life I would certainly have a problem with the lighting.
