Nice work! I really liked the opening and closing shots! Your photography is sick, very clean images! Nice sound editing, I loved that rumble sound during the second nat hit! The pacing was well done during the majority of the piece.
However to be nitpicky, the video editing was a little jumpy to me. I thought there could have been a few more cuts during the intense moments. You really shot it well, but some of the sequences were jarring and the edits just did not match well for me. For example, the shot coming out of the stand up and the cutaway coming out of the trainer soundbite, it broke the axis and it is a jumpcut. Just get a few more tight and reaction shots, and those can really smooth those edits out.
Again, nice work! Your photography is very polished.
