Thank you both! And, yes, i was referring to NaNoWriMo. I'm very excited.

I am planning to add more colors, particularly to indicate deserts and possibly other geographical areas. (I also have several other layers with information I need for the story, but those are mostly functional). Adding depth and texture sounds like a good idea too.

I'm still not quite satisfied with the mountains. I like them better than my original design, which was basically color-coding for elevation, but they still feel off - maybe adding depth to the rest of the land will help with that.
