I found the footage with the band a bit tame. Very static, the slow zoom out and in at about the 1 min mark lost teh bling which was there at the beginning.

So, my summary... The vid starts off really cool then seems to lose momentum.

I'm reminded a bit of Madonna's green-screen YouTube - Madonna - Ray Of Light which might give you a bit of inspiration, not so much the time-lapse as the ways she's chromakeyed, like your band.

Let's get one thing straight though, it's much better than the majority of "music vids" which get offered up here, so don't take my critique to heart.
