Needs More...
It needs more in terms of story. It is simple enough, which is how a short plot should be, but you can come up with something better than this. I understand what you were going for, but as others said, the music didn't seem right, and you could work on the animation more. The walk cycle seemed a bit stiff, now I know that you would say "that was the style i was going for," but the type of stiffness I saw didn't seem like a style at all. Don't let the bad reviews discourage you, though, be open minded use them to improve your skills.
To some guy before me:
Since when are cartoons better when they make little to no sense? Those may be entertaining sometimes and in some cases but there have been many cartoons that had a good plot and were still funny. A bad/boring plot or lack thereof can ruin a cartoon and make it less appealing. What is the point of doing something if it doesn't make sense? How can you express yourself through art and animation if they don't make sense? If all a person wants is to express themselves then they have no use for feedback at all, which you just gave in the middle of that rant. It is also possible for a person with more skill to criticize a less skilled person's work, so instead of insulting a potentially skilled person, you should just agree to disagree.
