Why upload an old animation if you don't think it's great? If you want to breath life back into an old animation, do an HD version or a director's cut. You could have redrawn scenes to have more details and shading, used a better converter so your animation isn't artifact-ed to hell, and recorded music with a better microphone so that it's not crackling when silent. Stop putting effort into making excuses for bad animations, and put effort into learning how to create better ones.
