First off, let's fix your link so people can get there...

Now, for the tunes. I love the video clip you used. I don't dislike the music at all. I think it's pretty good, but kind of simply too.
However when you put the two things together I greatly dislike the music because it has absolutely nothing to do with the action in the video.
A good soundtrack helps to drive the action in the sequence and when I watch the trailer with that music playing I just feel like I am on a drive to Grandma's house rather than watching an exciting action sequence.
Please understand that I am not insulting your music in any way, I do like it, I just think the presentation of it is wrong when combined with that video clip. The two separate things are great, but unlike Chocolate and Peanut Butter, these two did not come together into a Reese's Peanut Butter Cup for you.
Just an opinion, take it or leave it.
