Thanks for the input. The majority of it was made using Ascension's tutorial with the trees being added later using RobA's tutorial. I'm considering using RobA's for the mountains as well as I'm not particularly liking how they are currently looking. Perhaps I'll play around with the shelf layer to see if I can't make it look better. How about the different climate areas? This is supposed to be completely in the northern hemisphere (In truth, it would be a plane with no definite size as of yet).
