Air 30-Second Warm-Up

Done as part of a practice session with poses of 30 seconds in length. My current goal is: Make my forces of faces and expressions less stiffest and more dynamic,energetic, and fluid. Hello, y'all, this is my latest loosest warm-up of an expression. It's got the look and feel of a rough face. And, it's very funny. What do you all think? Is it least stiffest?? Is it drawn most dynamic, energetic, and fluid??? What can I do to make it excellent????
