Pointy Chinned Figure

Done as part of a 3 hour class. My current goal is: Reduce stiffness and make my drawings feel more dynamic, energetic, and fluid This here is yet another hyper-caricatured figure with a face shape. So what do you think of my anaylsis and intuition of the gesture drawing with an emphasis of caricature? How can I punch it up? Should this be a part of my portfolio??
