for the most part I Iiked it. just remember its all about the story.. make sure your story is compelling enough to work as an animation, and if the story is weak then the animation needs to be intensified to hold up against a non existent story.
Also Ive always been a fan of a ruff styled animation in favor of a polished one simply because you can see how the animator thinks through them.. But for the ruff style you used here there should've been way more animation. theres just too many sliding still shots for this style to work.
anyways you are getting better it and the cartoon was fun, so keep it up
