30-Second Fastest and Furious-est Animal Scribble

Done as part of a practice session with poses of 30 seconds in length. My current goal is: Work on my signature drawing style of sketching animal forces, gestures, and acting, most quickly. (advanced) This is my fruit of my labor, in which I'm working out my scribbly and spontaneous signature style of sketching animals. What do you think of this now? What can I do to help me strengthen my spontaneous quick sketches. by the way, I've worked, and I'm workin' in the smallest squares, all numbered for the time limits.
