I mean, it wasn't "bad" but ti wasn't great either. You kept using the same running sequence when introducing new fail. You could've at least changed it up a little bit.
Making your drawings and characters a bit neater wouldn't hurt either. Even though it's just a simple little flash, you still want it to be the best you can possibly make it. I've never animated something, but I do know how hard it can be. Even so, just try to keep things neat.
Overall, it's pretty decent! Keep up the good work, and you'll get better eventually.
