You've done a great job with the fluidity and the sub-pixelling in this piece, but I'd say it's too much.
The last and last but one frames on the left character don't seem as smooth as the rest, so it's pretty noticeable.
That being said, this is a good showcase of your skills and the characters are expressive, which is not easy to pull off
Iam surprised. I do not know there is animation in it.
Great work!
