Pretty cool stuff, but take the extra time and wait until you're 100% happy with the piece before releasing it. Spending a few more hours to do a better job grading and to get the ending how you want it would be well worth it in my opinion. I feel as though this isn't the first time I've seen you post a video up for a critique but mention that it's not actually a finished product or that you didn't put in your full effort. It's not that the content isn't good, it's just that it could easily be better with a touch more effort.
That said though, I really enjoyed the night concert footage towards the end and the interaction from the people throughout. Getting genuine smiles and expressions from the subject always adds a nice touch to a piece. I liked some of the glidecam shots in there as well, the one where you come up the ramp to the drummer made for some cool movement.
I wasn't a fan of the static shot around 2:30. Everything else has nice movement to it, so this clip seems very out of place. The lighting also isn't too great in it which takes away as well. Overall I would've liked to have had some ambient audio to help bring me in on another level. The visuals were good but I felt pretty detached from what I was watching the whole time because of the lack of natural audio.
Also, song. That horse has been beat. Something more original would've added more to the piece in my opinion.
Sorry if that ended up being a harsh critique. You've got a lot of great footage and I think with a little more love you could have a really great piece on your hands. Keep at'r.
