I can't say I'm really a fan of your video, in my opinion most of your ideas needed more work or had to be highlighted better. The story looked kind of rushed, the real red man comes quite out of nowhere. I would have liked to see him watch Ganta fighting for nothing for example.
Technically, I thought the cookie cutter you had to darken the video was hiding it too much. There are other means to make a video look darker, imo this one is disturbing and hides your editing.
Another problem would lie in the cam moves, I thought they were quite rough and I would have liked to see more movement blurs so that they would look smoother.
Overall it's not bad, but I think this could have been cleaner and thus better. Anyways, good luck in the contest!
