I love it

You have taken some fairly bland footage (with the possible exception of that 1 guy in the crowd who's 'over acting' skills are almost comparable to that of Jack Black:p ) and turned it into a interesting and fun concept.

If you compare your 1st effort to the latest, you can see how far you have come with After Effects in such a short time - and it's certainly not the easiest interface to come to terms with!

Job well done - I'd give it a B+

Dave.

PS: you gunna post your actual grade?
