Follow through with your project
I hope that you can continue this animation and challenge yourself as an artist!
I like the way you chose to animate your characters but the way that your scenes play out can become dull. Having the quick panning virtual camera was a good thing but go beyond that and use it to your advantage. Try getting a few more angles in each scene and come up with your own unique way to animate the moving mouths.
By doing so I am sure that your animation should flow so much better in the final product.
Good luck.
