24-Second Face Warm-Up

Done as part of a practice session with poses of 24 seconds in length. My current goal is: Make my forces of faces and expressions less stiffest and more dynamic,energetic, and fluid. Here is my warm-up. Making greatest progress, but with very littlest difficulites. What do you all think? Is it drawn fastest and funniest enough?? Is it drawn least stiffest??? Most dynamic, energetic, and fluid????
