27-Second Unrestrained Motion Sketch of a Figure in Underwear

Done as part of a practice session with poses of 27 seconds in length.

My current goal is: Get my forces of the figure bones and muscles, and their perceptions, to look or seem easy.

This one, if I do more of that pose, it would and could really move. Please give me some tips on how to post animated video files, because I'm asking for a feature request in the near future. So, how am I doing in the motion, and how vigorous am I?
