I hate to drop in with no studies to post (yet), but I've started doing quite a bit of drawing practice, including many portraits from life (friends at school). The likeness with many of their subjects is usually somewhat decent (they look alike when put next to the subject, but away from the subject you can still tell who it is), and usually gets that "wow" factor from everyone watching nearby (they aren't very great in my opinion, but I guess when one draws realistically and is actually somewhat successful, people see it as black magic).
Anyways, to my point: I'd love to start anatomical studies -- after doing these portraits, I'm extremely interested in the human face/head in particular, which would probably be my first subject of study. This might have been asked before, but since many people have seemingly found many great new resources over time... what would you suggest I study from that has worked best for the majority here? Thanks in advance! I'll be sure to eventually contribute some of my beginning study results soon. I'm willing to work as hard as needed, so don't hold back if you're thinking of suggesting "the hard way" to begin studying.
