That was the big thing for me. I really think that music could have worked, but it needed some parts cut out of it. Plus, the camera work didn't help it go with the song. Some of the shots where a little to far away from the car. With a slow motion video and such a slow song, you need really up close shots to keep interest.
I do think that song is just a hair to slow though, even for a slow motion video. I don't think you could make a video over 2 minutes (really probably less) with that song before everyone fell asleep.
Some of the shots were nice though so don't feel too upset. You just picked something that is very difficult to make work properly.
The camera movement in the first 'scene' is really cool but after that it's a bit too slow like the others also said.. I can't comment on the rest, the vid doesn't load completely Maybe if you speed it up a bit, and use different music, it'll be a world of difference
