Here is my animation from week 4 and week 5. The assignments were a heavy and light ball bounce (no squash and stretch enabled on the ball rigs,) and a ball capable of squash and stretch bouncing through an obstacle course. Both were limited to 120 frames. The obstacle course took longer than I anticipated, it's difficult maintaining those arcs and not going through the geometry while making timing and spacing adjustments.
Week 5 had a sketch/pose assignment due as well, we were supposed to show somebody feeling devastated. It kind of looks like he lost an eyeball now that I look at it, I should add one to his lower hand.
