There's a new kickstarter from anatomy for sculptors, concentrating on head and neck anatomy that might interest people https://www.kickstarter.com/projects/sandiskondrats/head-and-neck-anatomy-a-book-with-3d-augmented-rea I would consider their first book an essential read for anyone into character art, so have high hopes…
I have his first book. I was very disappointed he used the heads method of anatomy measurement versus the more correct version of using bony points of the body to get anatomy proportions. Being said, I might still kick in. The book was good otherwise.
Using bony points as proportional gauge is a new one to me. Did you have a reference? Google didn't come up with anything that looked particularly useful. I'll throw my support behind the Anatomy for Sculptors book. It's the best anatomical reference I have. Never leaves my desk.
