Extremely good! Not only does the picture has variety of subtle blended colors, the environment is unique in that it has very few things that could be found naturally on Earth and many things that are impossible on our planet (sideways stalagmites, strange patterns in the high rock formations that look like that were made by a giant worm, and floating spheres that could form perhaps due to lava eruptions and a concentration of gravity in matter). Perhaps I'm over-reaching with all this. Anyways, the art is great and I'd love to see something like this in a multiple player game or movie.
