It's... meh. Could be much better. I think it's mostly just that the music is bizarrely awkward. There's this darker loop which cuts off, then dramatic music, then abruptly it stops, then the first loop which is seemingly placed at random. With solid music all the way through, I probably wouldn't have been so distracted from the actual reason I started watching it... the trailer.
I've seen you use music clips well. So what happened here?
