Awesome job. You clearly have great cinematic ability.
The only things that hurt it are the 360p upload and the laggy parts. I can only think of one way to fix the latter (outside of buying a new computer):
Perhaps you can record the footage on Slow game mode or even slower (didn't some guy make a post about how to slow the game further?). Then in post-production increase the speed back to 24 frames per second or w/e. Maybe that would alleviate the in-game lag :)
