You should try and shoot reference so that you can get a better idea on how you want to animate your sequence. your characters lack weight to them and are floaty and robotic throughout. Lip syncing needs improvement.

In general, it lacks the fundamentals. I would suggest learning the simple "ball bouncing" exercise to start understanding the basics of animation.

Your camera cuts are ok, but I would study composition a bit more to understand negative space better. And you don't need the camera to whip around to the other side like you have at the end. It looks jarring. Just cut to that shot instead.
