Just excellent
As far as I can see, you make your point. The movement of the beginning of life to it's end is clear. However, I find that I do not understand what chee is enough to understand everything you put forwards in this movie. That is, apart from what you've already told the audience in your 'extra' option
Apart from your content; the graphics and music go together beautifully, I don't think you can get any better than this. You definately did an excellent job designing a visual for the intermixture of both chee and life.
