Not bad.
Good job not using stick characters; that's what really ruin a lot of beginners. Keep animating full characters, slowly trying to make them even more detailed, and keep practicing. The "animation" aspect - i.e the camera, the pacing, the easing, the story - was great, it's just the art that could use work (which is my problem too - I'm a terrible artist). Just keep practicing and you'll be a pretty good animator so long as you stay away from sticks and keep FBF'ing.
