Time Lapse??

I made the time lapse by after effects,
how was it??

The middle section is awesome, very nice time lapse and tilt shift. The beginning and end need some work, especially with the soundtrack - lots of distracting ambient background noise and the volume jumps up and down. The dark section with the second instrumental song at the very end should be cut completely as it serves no purpose.
