It's not bad, but not perfect either. I noticed there were some in-game messages, quite disturbing. Then about the camera's; in my opinion, and you're not the only one who does that, but you're using too much "impossible" camera's. And then I mean the cams which are following the cars, but are just hovering in the air. You also used very much the standart cams, that's not wrong, but this way the clip hardly gets an identity.
The idea of the beginning is nice, but it's not convincing. The texts are either meaningless, or said in the wrong way, so the message doesn't come over clearly. Then the sounds are a bit "weak". That heart-beat isn't really a heavy sound which sounds attracting, it's just a sound. And then you see part of a race. Which is nicely done, but imo too clear. And the difference in loudness of the sound is too much.
And finally the clips don't really go with the music. In big lines it's nice, but the details are missing. A spectacular climax doesn't only have to be reached by fast camera switching or full-speed cars, but also by the way it gets on the screen.
For example, 20 cars viewed from very far away is just as special as 1 massive car in your screen. So, imagine what it looks like with 20 massive cars in the screen, they don't all have to fit, as long as the viewer know's there are 20 cars there.
Hope I'm a bit clear, since it's already late. And not that I disliked it, but now it isn't really that special imo.
