27-Second Hands And Feet Grayscale Warm-Up for Quick Sketch Animation

Done as part of a practice session with poses of 27 seconds in length.

My current goal is: Improve my understanding of hand and foot bone structures.

Here is my scribbly warm-up sheet. As you can plainly see, I'm really loosening myself up for my gesture and ruff animations for my animation test. As you can examine, I'm just going for the speed and the soul of the models, instead of the quality. What do you think??
