"Action!Cartooning", by Ben Caldwell, is a great book on drawing cartoon figures. I am a professional caricaturist myself (I own caricature concessions in a major theme park, and wrote the book "Let's Toon CARICATURES"), and a lot of the info Ben gives about "pushing" the characteristics of your characters, in order to give a clear, instant insight into their personalities, can be applied to caricaturing as well. There's a lot of great things about this book, and a lot of beautiful drawings. If you want to learn to draw good, cartoony action figures, then this is the book for you. It is so much better than any other cartoon or comic book anatomy books on the market, that is isn't even funny. I have recommended it to all of the artists I work with, and many other artist friends, already. I'd like to know what else Ben's done, because I'd love to see more of his work!
