Quite entertaining! Such smooth animation. Would have been great for madness day. :D
I really don't think there is anything to improve on, although you can always add effects beyond preportion. If you were to do that, you may get more fans or views with a simple slow motion and blur effect. Even consider some 'matrix' style movements.
I'll take it in count in the remaking of an old movie of mine ;) it's named madness crate
