The great thing about drawing Oz is that I have plenty of pictures I could use for books. Say one of my writers mentions Jack Pumpkinhead. I could find an unused picture of him like this one and put it in the book.
If you are an artist who is a fan of Oz, you are probably influenced by John R. Neill. Even though I love the Oz stories, I think I was more interested in Neill's artwork than Baum's writing. My style is no where near the kind of art that Neill did. I do prefer drawing in my own style, but I thought I'd try and draw a little more like him. Right now I think it's still a pale imitation of his work.
