16-Second Caricatured Face Grayscale Flipped Upside Down Warm-Up Sketch

Done as part of a practice session with poses of 16 seconds in length. My current goal is: Improve my understanding of my caricatures, exaggerations, and satires of my faces and expressions, mostly for animation designs. Hey everyone, I'm back. Back with my first ever caracatured face sketch. Pardon the scribbliness of my warm-up, but it's just here to loosen me up. When I do animation character designs, I like to work very loosely first, so I get every force in the right place, in terms of flow and spontaneity. What do you think?
