Good energy in the wrong place
Maybe its my preference talking, but I don't think sprite based animations are any good. Even if your drawing skills are limited, its important to develop them, instead of relying on artwork from others to put something together.
You are right, Akira is one of the more popular anime movies, and oddly enough, a lot of people I know who don't like Anime LOVE it, I'm sure you won't have an issue with people recognizing it.
If you put this exact same effort into drawing a animation as a tribute to the movie, even if it was a quarter as long, it would do a lot better. It seems that around here most people only like the sprite stuff in comedy, and its hard to take seriously.
