Yeah, I started putting more attention to the anatomy of facial muscles and tried to work out how the skin wrinkles and such. Understanding how things work helps a lot with painting them. :D
Have you done a study on just the muscles under the skin and how they work together? You could look into that to get a better idea of how to shape anatomy of any body area. I need to do the same thing myself haha.
I mostly just did photo studies and reading anatomy books. The most difficult part of studies in my opinion is finding the resources. (x
I would love to watch a dissection of a striped hyena some time. (:

Amazing detail, proportions are spot-on and the fur looks realistic. Awesome job! :)
