In the field of digital Anatomy / Sculpture, probably wouldn't hurt to have a peak at a bunch of resources authored by one of the discipline's founders, as well. https://www.scott-eaton.com/anatomy-for-artists-online-course
It would also help to study anatomy and proportions. We have a ton of great resources, cached here: Anatomy Reference For example, PoseManiacs has excellent references https://www.posemaniacs.com/tools/viewer/poses/01H6RBJ01K4AJGPMCEYW5FKYFZ
@disanski I would't use a single artist as a source of anatomy because your going to inherit their mistakes. Here is a comparison of Zack's and Scott's anatomy. And here is Ryan's male anatomy, which he seems like it's midway of Scott Spencer's and Zack Petroc's
For drawing anatomy, I'd recommend any of Bridgman's anatomy books, also Loomis' Figure Drawing book is very good but hard to find a hard copy of. I've heard Sarah Simblet's "Anatomy for the Artist" is a good one, but I don't have that myself.
