I worked on my second map today and came across an issue I couldn't really solve to my satisfaction yet.
How do I draw deserts that look like ... well ... deserts? Both deserts I planned lie right behind mountain ridges in an otherwise humid, tropical to subtropical landscape but I can't get the sand to look like actual sand. It just looks yellow and not integrated at all. Do you have any tips for me (or any advice for improving that particular map for that matter)?
