I used quite a load of sources as reference actually… mainly medical stuff, like anatomy books, dissections, 3d CT scans, X-Rays… Anything I could get my hands on for free. Some art-anatomy books too though, because they outline the actual form of everything rather than just where and what.
Check out Acland’s video atlas of human anatomy for dissection reference (it really REALLY helped me).
Bammes has great books aswell
I haven’t seen any seminars from Ryan Kingslien, although I really want to. I watched some clips of him on Youtube and learnt a load of things just from that.
If you want to learn anatomy as fast as you can, I would recommend making one these, it has really helped and it commits so much more to memory than just studying out of a book. I mean, you don’t even have to put in as much detail as I am going for (I’m doing it to put on my portfolio), you will learn as it all comes together; it did for me at least. I guess alternatively, you could focus on sections of the body instead of doing the entire thing, or draw it out.
I can’t say that I now know anatomy 100%, but I definitely have a MUCH greater understanding of it. Once you’ve got an understanding of the human anatomy, you can adapt it to pretty much any mammal and most other animals too.
