Not bad, I can even see you used Flipnote Studio 3D for your animation as well. Plus, I even use it all the time. Overall, great work.
Decent animation with a very simplistic style, you clearly haven't mastered animation yet, but that's ok! Everyone has to start somehwere after all and if you keep on animating you'll surely get better.
Although, I greatly suggest you slow the pace down and focus on making the transitions better because i couldn't really understand what was going on at all. The viewer is just catapulted into a convoluted situation that's unfolding without any explanation and a confusing conclusion, the storyline seems almost nonexistent.
For improvement you can watch and learn from films made by Disney and some tutorials you can find from old Disney animators such as Aaron Blaise.
