29-second face warm-up

Done as part of a practice session with poses of 29 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 first flipped 29-second face warm-up. I'm really paying attention to the gesture of this face. I've really made even more than greater progress in my facial gestures against my self-perceived limits here. What do you all think? Is this drawing least stiffest enough?? Is it even more than most fluidest???
