Face 24-Second 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 latest forceful face sketch warm-up, right here up above. As you can plainly see, I'm really making greatest progress with my current goal, yet, I'm having too little difficulty on reorganizing my warm-ups on paper. What do you think of this one?
