Sorry.... didn't get it
There are three main components in a good movie, graphics, music/sound and story.
I should say that the story is the most important, but sometimes the other two aspects dazzle the viewer enough to make up for the lack of a good storyline. One example is a well done music video.
First off, I think there is not much of a story in your movie.
Graphics-wise, the background was well done, but other wise a lot more can be done to the characters and the visual effects.
But the sound was good enough to be unnoticeable. (That's good! Because you wouldn't want sound effects to be so bad that it catches the viewers attention too much.)
Anyway, good attempt. Hope you do something better.
