I enjoyed this, and I'm not even an especially big Marvel fan. It's the perfect length and feel of a "declassified" snippet of information, teasing the audience just enough without feeling too rushed or over-long. The lighting, set design, effects, and voicing is spot-on, you did an excellent job in those areas.
However, I do have a pretty major gripe with the cinematography, and feel that it bogs down what could have otherwise been an excellent short. For a start, you've broken the 180-degree rule multiple times (most jarringly at 0:31), for no discernible reason, making the cuts feel choppy and awkward instead of smooth and flowing. There were also some unnecessary cuts, such as the one at 1:11. I think that it would have been beneficial to have a few more close-ups on the faces of Coulson and Hawkeye, instead of always framing them in medium-wide shots. Also, the introduction of the Gambit/Hydra files is a bit awkward too. Personally, I would have shown this file show up on a screen on Coulson's desk before cutting directly to it--this would have again made the film flow more smoothly.
All in all, some great things here, but I still feel that there's a good amount of room for improvement. Good effort, though!
