hmm, well the filming was great and i liked most of your shots, but overall it was boring. the pacing of the whole thing was a little slow. i know its a mellow song and all so that wasn't as big of a deal. maybe some more shots cut in of some b-roll type stuff between key verses or lines to kind of keep the viewer interested.
my biggest pet peeve was the color of the whole thing. i didn't like it at all for that video. i know you were trying to go with a black and white "real life" to a colorful "dream" but it looked too plain for me. its like there were three main colors in the whole thing: green, blue, and gray. I feel like if you were to push the grading a bit more one way or the other, it could have made it a little more aesthetically pleasing.
that being said, i think the glidecam shots were awesome and used perfectly.
