Exactly what it says on the tin. I'll be splitting it up with different categories. Feel free to comment with more links!
Human Anatomy Guides (aka, how to draw people)
A note: some of these anatomy guides can be difficult to follow as a beginner, as they dive right into the form and structures of different muscles and bones. I suggest trying out figure drawing and learning 1, 2, and 3 point perspective if you're having trouble.
