"Artistic Anatomy" resource

This is a great collection of a variety of highly detailed anatomy for artists' reference. Not only is it human references, but also animal/skeletons, implements like bows and arrows, and things like skin tone gradients.
Excellent stuff.

nsfw warning of course, but surprisingly, there's not an overt amount of nudity present. Lots of shape/volume sketches, and individual body parts in detail.
