Using Utility to Make My Own World

I used the program Utility to create my own world.
Using a tutorial for help, I created a terrain using this image from Google:

I took it into Photoshop and upped the contrast and lowered the brightness. Utility takes the brighter parts for higher elevation, then creates a terrain like this when imported:

Next, I went ahead and added textures to the terrain and to the background. However the texture process was very difficult and I wasn't able to correctly add clouds. Here was the final shot from a lower perspective:

I thought this program was really sweet, and I would love to work at it and learn more about how everything works.
