Like all of Chris Hart's books, Cartoon Cool is filled with hack drawings and bad drawing advice.If you really want to draw in the Retro style, here's a tip: Go look at the cartoons and the artists that inspired the retro style in the first place. Ed Benedict, Mary Blair, M. Sasek, 50's era Hank Ketcham, Gene Dietch.These are the people that Craig McKracken and Genndy Tartokovsky and Lynne Naylor are inspired by.Google the names. You'll have a wealth of material at your finger tips.Here's another tip: REALLY learn how to draw things the way they really look.You can't abstract something unless you know what it looks like.
