Here is an example of what you can do with the textures:

I used the soft moss and orange rock 5 textures.

There are tutorials all over the web on how to use textures but unfortunately I don’t have links to any handy (I recently downgraded my system from Vista to XP and lost all my bookmarks – no idea where Firefox stores them). If you’re interested in me writing some basic instructions out, please comment here.
