So I am starting to learn how to use Terragen 2 and this was my first terrain image to come out of it. I'm pretty pleased with how the landscape came out; I think it looks very much like a moon.
Other then that I was trying to keep with "cool" colors like different shades of blues and some green.
The planet is far away from it's sun which causes it to be mostly frozen and it has 2 moons; a closer one and one farther away which the image is taken from.
Used CS5, Apophysis, and Terragen 2. Hope you enjoy.
