My boss inspired these Tarzan sketches I did the other night. Not because he swings around the office in a loin cloth (even though he does) but because he's working on a Tarzan illustration in his spare time. I was really drawn to the challenge of drawing a man swinging through the tree tops in both a dynamic way and also a believable way. What do you do with your legs when you swing like that? Some ape videos on youtube were really helpful.
