I think the flashback scenes should be done all in one color. I think the blue-to-red shift would look a little tacky and forced. I also disagree with the idea of using quotations from the film in the end credits. I just don't see what's accomplished there.
However, I love your paint job on getting Dan out of the picture in the Arctic. I think you should sign on to help Ash with his edit, just to work on that scene, and let Ash do the rest of the flick.
