The past many days I have had so much fun with those quick poses and posting on Tumblr. Watching what other people draw and getting a bit of feedback is really motivating.
So today I did the quickposes for around half an hour, 60 sec/pose. I then drew one pose with no time limit. That one was fun too. I might break it up like this from now on, doing a bunch of fast poses first and then one drawing, where I can play with shadows and refine the form and movement a bit.
