I did the ones above yesterday and went way over time just trying to understand the poses - yikes: some of these were so hard! That foreshortened arm is a doozy - I had no idea how to understand / represent it, and I really struggled with almost everything in that crunched over pose. And the bent backwards head. 

I tried again today to do a few closer to the time limits (below). I found them very frustrating, as I did not remember much, and I feel like they all stink! I envy watching you draw them as your decisions are so much better from the get-go. I just can't seem to see the angles and relationships properly until I draw them wrong first.

Anyway, I'll keep trying.

I can't wait to see your foreshortening course!
