Nice job... iffy lyrics.
Good and okay things about this... the music itself works pretty well... your harmonic choices (modal shifts/secondary dominant chords) are very nice. Your singing isn't bad for an amateur! Pretty good pitch, if a little too hammed-up on your embellishments.
The lyrics were a little weak... sometimes they made a good point, but things like the four leaving "this town." What town? Aren't they in every town via TV? Do you mean Hollywood, or do you mean "hey, this rhymed?" And Tom Cruise? A "fool?" We should all be able to dig a little deeper than that, he's got plenty of insanity to write verses... no, full-scale operas about!
Your video was hilarious though. Bus hitting the cannons = Priceless humor. Awesome. That made the entire thing.
You've got a good idea of what to do, and you did it pretty darn well for someone composing a song, performing a song, and composing a video for it, and animating that video. That's a shitload of work. I just wish you got maybe a second or third opinion on the song, and especially the lyrics.
