CONGRATULATIONS!!! Not only is this your first animation but it's a completed one. That's a big step. And for a first animation, you did great. You tried creating a story to create emotion and one that people could relate to and that's great. A great story with bad animation (not that yours was bad) is usually much much better than a great animation with a bad story.
I can't wait to see your next animation.
Don't be satisfied with what you can do but rather strive to do the things you can't do!
Exceed Expectations!
