I'm the last person to talk about art, but from a technology standpoint I think the end result would have been better if something that supported keyframes was used, like https://www.synfig.org/ or blender.

Keyframes would have made it easier to have 4x the number of frames making it smoother and easier to tell what is going on. Also, I'm sure it would have been more work to get started, but building up vector versions of things using bones would make it easier to put together the 2nd+ animation.
