The kicks upper body was stiff, but you said not to pay attention to it so I wont, the trails were fine, nice work on it..
The spring test was pretty simple, no real flaws..
I liked the flip animation, the physics were pretty good, but he landed in kind of an awkward position..

Keep em up

You said about the newest that you didnt focus on the upper body which explains why the legs and trails were the best bits, the kicks are smooth and flowing, and the trails are well animated,
in the spring anim, the stick could do with some more movement, perhaps walking onto a spring and not knowing it is there, but the sping looks pretty realistic especially the way it goes back down to show momentum,
