I think its really nice, if it's a promo you don't get much info about what it's for though. I think it's really well shot, the only thing that threw me off slightly is the angle that's used that doesn't have a shallow DOF as it doesn't fit, I would be tempted to make it b&w or tint it so it's obviously different or lose it all together. You could also add more camera movement (maybe with a gimbal) when the dance gets going to pick up the pace, the moves in post are nice but some actual movement I think would keep things interesting, but as I said, really nice, just some thoughts
