Nice, also liked your other "trailer" video of season finale.
If you want bit critic:
In the scene of Aston chicane it shows the moment when the tire barrier resets, something strange looking that can be avoided. The first half is basically stationary cars..when the first moving cars are shown the video is already half over. (Maybe that is why some posters feel it too short)
For that intro-ish thing before lights go green you could use scenes of cars leaving pitlane/garage or so. (from qualy replays)
