I'm going to rate this on the movie, not the song.
You didn't make the song, only the movie...so I'm going to review this based on the movie:
This could have been a WHOLE lot better. The graphics were sloppy and mediocre, while the animation was choppy like a slide-show. What I want to see is something that's worth watching with or without sound on.
There wasn't nearly enough movement or lightheartedness in the visuals as there needed to be in order to measure up to the song, which is why this gets a low score from me. Had you put some real effort into this, it could have been really good, but what I saw was far below my lowest expectations.
