Compellingly mysterious. This has a very alien look to it. I'm not sure about the bright line at the horizon, but perhaps I'm missing the point. It doesn't really suggest creation to me, but that might just be me and doesn't detract from the image anyway. Very good job.
Very cool image, just the render was really sketchy. I think you should work on making everything more dense, and smooth, and also lower the gamma just a little bit, and submit the new version. I think it would look alot better.
Interesting effect. I think it's a good idea to familiarize yourself with the individual aspects of TG rather than leaping in head first as most people probably do. Maybe this one is a bit dark for most tastes...
