This is unfortunately not good enough to really pass the judgement. But I do love the fact that you've tried this animation style and that it turned out not as horrible as maybe just some random stick movements for like 2 secs.
You should try to really improve the length of your animation, this is in my opinion like the #1 mistake that most of the beginning animators make on this site. Make it like atleast 1 minute. Or maybe even longer if you think that you've got good ideas. Very early and unfinished demos aren't really the things that a viewer would love to see. Also, a few more details throughout the way would be neat as well.
Anyways, I really hope that I could give you some small, but atleast helpful advice for the future that you'll be able to utilize well in your upcoming projects. Just don't give up, I definitely think that you could create something really cool with that! ^_^
