23-Second Flipped Face Warm-Up

Done as part of a practice session with poses of 23 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 upside down flipped face warm-up sketch. What do you all think? Are my forces of my faces less stiffest?? Are they most dynamic, energetic and fluid enough????
