Not bad at all, just a little constructive feedback:
1: When the music goes boom and it's ready to roll, it would be much better to have the starting scene with a race, rolling start, crash, close racing or something. Starting from the pitlane is a little dull to be honest
2: There are some audio problems, specially on the part where the FBM's are roaming down the straight.
Other than that I enjoyed the end of the video, and liked it violent / action theme
