Lose the fisheye. If you're zooming in far enough to get rid of the vig, you shouldn't be using one.
In terms of shot selection, the people above me are 100% right.
To sum it up, you have to think of what you're trying to portray with your edit. Are you trying to showcase the skills of your friends? If so, don't show them knuckling/fall off rails early. The only time you should do those is if its a joke. If you're trying to showcase a fun time, then you should have chosen a different song (you should have chosen a different song anyway - your song should fit your material and generally should appeal to your audience, as that will increase the positive response from your video. That does not mean use popular songs.).
Honestly I found it hard to watch. It seemed like you guys were trying to be too serious - to the point where you could have been joking.
In terms of videography, a lot of your shots were basic and there wasn't much smooth camera movement - pans, tilts, and dolly motion - to supplement the subject.
In all I would keep working on it, but consider your audience next time. Think about what you're trying to show with you video and keep that in mind while you are filming and editing in order to put out the most accurate finished product.
