Sometimes I think cartoonist are the most artistic realm around. They have to draw the little things, such as where to put a hand or a facial expression before the major part of the cartoon. I am looking at her hand covering her mouth and realize that has to be drawn before the facial concern expression she is showing with her glasses. He has to see the entire comic in his mind before ever laying his pen to the paper.
I had to look it up, and I gotta admit, the walking tree does look like it is walking. Eerie!
