what Andrew said, and on top of that, you'll want to edit out the pauses at the beginning and end of the clips so make it more seemless.
It was a difficult transition for me, that I really only made in the last couple years, but don't have the video be in slow motion if you want it to flow better. That doesn't mean have it be fast but unless you have a really mellow song, dont have it all be in slow mo.

And finally, always test out the camera angle before you start recording, use that to prevent players from disappearing and those "whoa" closeups.
But as Andrew said, it is a good first attempt and there is a lot of potential, good luck!
