29-Second Expression 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. As you can see, I'm really improving on my drawing the face and expression forces here, so I'm having very little difficulty, and there will always be room for improvement. What do you think of this? Are the forces of the face least stiffest?? Are the forces more dynamic, vital, energetic, and fluid???
