Not bad for a first video, there are some things i like to point out though
Make sure you adjust the clip length after changing the velocity ( 1:30 for example, the clip repeats itself.
Fade out after a clip and fade in for the next one, the transitions are way smoother if you do. Vegas has some cool default transitions as well that can easily be changed to your needs.
you can change the speed velocity multiple times during a clip ( I'm assuming you are using sony vegas ) if you double click the green velocity line, this way its easier to sinc to the music.
Its good to give credit to the people involved, but the long list might have been better if placed in the end.
I dont know how you recorded the replays, but if it was fraps set the frames to 60, looks smoother and the average speed of the replay goes up.
( Sorry if your comp cant take that :P )
All in all you did a good job and if you take some of those advices into consideration, i bet you are able to make really cool videos in the future
If you have any questions about Sony Vegas, feel free to drop me a pm (after watching the intro again i'm certain you did use vegas ;)
So yea...rating.... lets say a 6.5/10
