24-Second Flipped Upside Down Force Face Warm-Up

Done as part of a practice session with poses of 24 seconds in length.

My current goal is: Improve my understanding of the forces of the facial skull, in terms of my facial anatomy.

Here is my latest force face, flipped upside-down, warm-up sketch. I'm really, really having a blast at this process. It's not that good. But the idea is there, and it's of a happy african-american man. Please comment and share, and like.
