I actually meant to do hips and crotches, because those really need work. but the anatomy book opened on knees... and I never made it. kind of sad, in a way. :)
seriously. knees are hard. the kneeling one is by heart, the rest from my book.. and after all that,
I'm still not sure if I got the lower part of the joint right.
the hips I did start on. but the book was a little less clear on that. or, at least, I found it confusing. showing different viewpoints without
making it clear which angle we are looking from.
no worries, I have quite a few books. ill just pick another one.
