Nice vid, always liked the idea of putting live commentaries in "artistic" vids. The best example is of course David Novak's 2009 iTCC Highlights. Too bad the concept is so much underused, really. I would say it doesn't fit as much with endu racing than with touring car racing, but it's still a fairly nice idea you got there.
There are some other voices I don't know in that vid, TS/Vent recordings of the race I assume? If that is, good idea, but perhaps it would have been better to work on those sounds, perhaps reduce the sheer quality at least, to make them sound different than the live commentaries.
Good job apart from that. The music is fitting quite nicely. Some scenes are maybe a bit to long on the other hand(especially for Dennis' spin). The FOV of the onboard camera at 2:37 is probably to much big to look realistic also. The rest is fairly good anyway.
