You have a good song and good idea
The only thing that ruined it is that you used static images or looping animations that were obviously copied and pasted and don't really do much. I mean if you want to portray elves that are pissed at santa at least have them do something besides stand stiffly in one place. Put a little more work into it, ok? And maybe you might get higher scores if you animate something more interesting like the elves rioting and burning down the toy factory.
