Can't Apologize for this Warm-Up, Just Loosened Up My Perception.

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 upside down mirrored grayscale face warm-up, all done in various colors. I'm just really best focusing on the forces of my facial skulls. What do you all think?
