The animation is great, it has a lot of frames and has some snappy moments. However the pace of the animation feels off at times, and makes the whole thing feel akward.
Some of it feels faster than it should be, some of it feels slower than it should be. I would also chose to focus more on the frames that are important, like in the end, it feels like it goes back way too fast, give the frames some time to breathe, so the animation has more impact and the viewer has time to appreciate the animation.
I would suggest you storyboard next animation to have better pace, what you have done in such time frame is amazing, but it can be improved with better planning.
