Expression 26-Second Warm-Up

Done as part of a practice session with poses of 26 seconds in length. My current goal is: Make my forces of faces and expressions less stiffest and more dynamic,energetic, and fluid. Hi there all, Polyvios Animations here again. As you can see by this 26-second warm-up, it's pretty jaw-droppingly scribbly and looser. Is this expression least stiffest? Is it more dynamic, energetic, and fluid??
