Like others said, the song has been used before. That doesn't make the video bad but it does make it bad in comparison since the one made by sly and avi is one of the best ever made.

So basically try to look for songs that nobody has ever used before.

Also I can't see much sync, try and sync every hit.
The tempo of the music doesn't fit the pace of the video; High tempo = Fast Pace

Yeah hit the gas pedal on the replays man. Try to get closer and more creative with the freecam. You should definitely stick with after effects. I started with Sony Vegas and its sooooo hard to switch to after effects which has more things. Nice replay and shader choice though.

How on earth did you get those good camera angles?

Replays were nice, there was some sync but not much. Also you could do alittle bit more with editing and angles. Though good job.
