I've drawn lots of dinosaurs in my day but not many dino skeletons. After settling on a composition, I set out to learn the basic mechanics of my fossilized friend. I did this by studying dozens of dino, rhino and elephant skeletons.
I'm a big fan of the "drawing through method" which simply means drawing things as if they were made of glass. So rather than draw a big dino skull and guessing where the body, legs and tail might fall, I drew every body part, whether it showed in the final illustration or not. I then combined the bits and pieces in Photoshop and voila!
"Drawing through" gives me confidence in my work -- and I hope it translates into more believable illustrations. Here's some early versions of the illustration.
