Very well done indeed. Gave a great feeling of being there and seeing the action as you sure captured the moment. Loved the music choice as well as James Bond movies have always been one of my biggies. It is indeed an unbelievable feeling having these sharks around you in the water and seeing what they are capable of. I was able to do this once in California many many years ago. I cannot remember what types however.
As far as your artsy part... I think it showed at the very ending. It is a trial and error type of things sometimes. You have a great start here and look forward to seeing more footage as you progress.
