The world needs less stop motion people.
I'll give you some credit for style, as it really was very different from most of the crap submitted. However, the animation was not the best, no sound (Big no no) and it was insanely short. You need to work with the program that you are using. My first submission doesn't have very smooth animation either, but after that I experimented and figured out how to make the animation smoother. Also, if you're really dedicated to this, you can't just spend 6 hours and expect to be done, you have to put a lot of time into it. Anyway, like I said above, I really disagree with the last guy, the world needs less ordinary people dabbling in the arts. Anyway, keep working on your stuff, put a little more time into the next one (please put some detail in characters and backrounds) and you should be good.
