This can also be achieved in other styles by increasing the size of the mountains and decreasing the size of the trees. I use this technique a lot when working with Mike Schley, for example.

One option I often use on my overland maps is to change the internal glow of the SHEET land to a lighter color (I usually use #29).

This color can simulate a "beach coast" in a simple and quick way.

Another way to further emphasize the coastal aspect is by mixing in other types of vegetation closer to the coast, as in the example.

Very good detailed work with overlanding for the short time you were willing to do it!

Usually, short time (sometimes rush or anxiety) and art don't usually go together. However, perhaps the thing that takes me the longest at first, at least here, is getting to know the program and automating my work sequences.

Once the "automatic" (while operating the basics of the program) is turned on, the work always tends to be much faster.

Some time ago I made this mini tutorial where you can quickly, in this case develop a sequence - at least for me - practical to work quickly. When I exchange city - in this case - for overland, the basics of my procedure remain the same.

Maybe it can be of some use to you.
