27-Second Grayscale Face Scribble-Warm-Up sketch

Done as part of a practice session with poses of 27 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 warm-up sketch. I'm just here to get ALL my mistakes out of the way. I'm also just getting out a lot of bad sketching, and bad drawing, without pressure. Just doing what I do. Doing the job as effectively as I can, and the best I can. What do you think of THIIS??
