Since this is an animation from 2016, this might explain why the quality isn't as good as it should be. With that in mind, I'll assume you've improved your work.

The positive points of this are that the main character designs are super creative and the story and gags are funny. In spite of that, the animation as well as the overall needs a lot of work. Regarding the former, you didn't use a good amount of hand drawn frames for some actions, while depending too heavily on basic motion tweens for other actions. As for the latter problem, your artwork looks like a bunch of scribbles with the paint brush tool hastily filled in with the paint bucket. Plus, the color palette is way too much. If you tidied it up without sacrificing the visual style you're attempting to portray, then you might have an appealing animation on your hands.

If you created new animations in recent years, then I'd love to view them and judge your progress.
