Peter of Narnia

I'm trying to figure out some basic shading problems I've had. So I'm experimenting with this sketch. I thought black & white would be the easiest to manage, without all that color to worry about. I learned quite a bit from this exercise, various dark and light placement and such... I added a couple darker highlights to this, gives it a little more depth.

Some people sketches

These are just some random sketches I did of my friends, with some design "hoo-ha" around the outside.
