I worked on some keyframe composites representing a reimagined fall of Reach for an article written by my good friend Joseph. You can read it here: https://goo.gl/UuHb6p
This was a joint effort. I was provided 3D renders from Source Filmmaker from both the author of the article and another Halo community member MetalHeadSpartan. I used those elements to build the final composite in After Effects.
