that was a good first try...a few things to try to fix is the stuff visible in the video, like the gauges, and the tire temperature, and chat still visible in the video.
also, you switched views during the clips, that is a big no. try to get the view pre determined for the clip, and keep the movements fluid.
when you switched off clips, you used some crappy transition effects, you should stick to the more neat, and better looking ones...my favorite is fade to black and then fades to the next clip.
