So, after some period of inactivity, I have learnt how to make my mountains. I also learn of a new technique among those high class worldpainter/worldmachiners called masking, which makes VERY realistic maps.

However, this technique did not work out on here,so I decided to apply my newly made mountain brushes on this map, while testing some of worldpainter's new stuff they included in their new update, and here are the results. I decided to render using Eihort, which is a awesome programme you should check out.

Also, expand your brush size when you make mountains.
