This is amazing, I need to see more. It's not just the quality of the rending it's the music\soundfx and the story that goes along with it. What's the dome in the background? Will you be rendering more?
I love how it transitions from the lush grass and trees to the desert wasteland.
The weakest part for me, if you mind me saying, are the clouds. Not so much how they look but how they move, I think they need to warp and twist a bit more as they move across the scene, and maybe slow them down a bit. Other than that I think this is a really interesting project.
