Preparation for CalArts: 50 feet Life drawing challenge

So ive started up the weekly life drawing challenges again in preparation for CalArts and started off with 50 feet. I'd done something similar with hands a while back, but ive never spent any time looking at the structure of feet, how they bend, move, stretch, curve and just drawing feet.

It was nice to do something new and i figured i'd try out a few different techniques, changing to a different technique every other page or so. i feel ive definitely improved with how i draw feet so hopefully that'll show up when i attack a full body figure again.
