Nice job Dustin! The exposure/colours/grading looks great.
I didn't think of it while I watching, but there were a couple of moments where I was struggling to understand how big it was, particularly the wide overhead shot at 2:20, where it could be anything from Spitfire size to jumbo jet size. So I agree that a diver or two in shot would have helped.
Also, people in underwater videos usually helps the view count. "People-doing-amazing/adventurous-things" videos are hits on YouTube/Vimeo because viewers relate to the divers in the shots. Escapism!
For me, the music was slightly too epic for the scale of the subject. But as we know, music is really subjective, difficult to find, and you can't please all the people all the time.
