18-Second Scribbly and Loose Figure Study of Vitality and a lot of Energy

Done as part of a practice session with poses of 18 seconds in length. My current goal is: Make my figure suggestions less stiff, and more dynamic, energetic and fluid. This is my first ever quicker figure drawing, done more quickly than ever before. It was done fast cause I've sketched the sketches like I've really churned them out. The beauty of these is that I'm really thinking about the acting that's going on the paper. What do you think of this?
