My comments:
Would have been good to see some racing, not just the start of the race.
Sometimes, the FPS got a bit choppy, see if you can get that sorted.
Edit the music so it gets exciting sooner
I liked the fading between the grids
I liked it when the music was synchronised with the changing camera
There needs to be more custom camera angles that move and follow the car
You need a close up of the lights as they change
Get rid of that watermark of GameCam!
Just my opinion of course, you don't have to listen at all
Room for improvement, but a good start!
