I have no idea how you made this. As far as I can tell this is actually in 2D, which is awesome and very impressive. I think it was missing a lot of visual flair/polish, like the lack of explosions and helicopters moving in front of very close trees.
While the 2D was impressive, super awesome, and I applaud you for accomplishing it, it was also extremely disorientating. It may just be me or it may just be sleep deprivation, but it made me nauseous and gave me a headache, and I've never had that happened to me before
