26-Second Expression Warm-Up Sketch

Done as part of a practice session with poses of 26 seconds in length.

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

This is last night's newest expression warm-up drawing. This is really broader and loosest in terms of the line economy, and in terms of the minimalism of how fewest lines I can draw out. Love it?
