Spent some time fiddling with mountains and rivers today. It's pretty rough right now and I think I will probably be re-working the distribution masks to give a more erratic shape to the mountains. In a similar fashion, I will likely extend the rivers further up into the mountains. Will have to see how it looks after a larger render, but for now, here's a sample of what I managed this afternoon. I'm definitely looking for some thoughts and opinions on this one as I am only about 50/50 on how it looks both for shape and coloring.
