I liked it, it was good. As a promotional video I don't know if it holds up that well. The music, to me anyway, just doesn't fit with the trailer. But could just be a personal thing, you'd have to get a few more opinions jsut to make sure. The choice of music is so overpowering that it takes away from what you're trying to sell. The clips on the other hand seemed to be edited together just fine. It was easy to follow and I didn't get confused where you were going. May I ask what you're planning to use this video for?
Other than the music(which could just be me) this video is alright. Keep up the good work!
