Sorry Anaxetogrind, I forgot to mention that the map is made with Photoshop. CC3 was used for the contours. Clouds, clouds, clouds. Of so many layers does the ocean consist and at the top an ocean ripple filter. No chance to redo it with CC3 as I think.

Thanks Wormspeaker, simple is just the right word. The regional map was quickly done and I see that I must spend much more time in drawing new symbols.
