WIP Update:
So, the otherwise very mean gods of Kharoun have been merciful and sent some rain to the arid lands...
I put some green in the deeper rivernear and coastal areas to crack up the monotone redbrown of the map. Thanks THW for the useful tips! I had to adapt a bit in Gimp, but i'm somewhat happy with the outcome.
I also played around with some city-textures i created. In this one, i applied a texture i made (through lots of filters in gimp) from a picture of the medina of Marrakesh on the southeastern cities of the map.
I'm unsure about that: it looks pretty much how i like to have it, but i was struggling with the question, whether this (to work with pictures in general) is a "taboo" in the honorable art of mapmaking??? What are your thoughts on that ? My rationale was, that this map isn't a city-map, so the cities on it play just a minor role. Usually i love to "do it all by myself", but (till now) i couldn't imitate the organic feeling coming with the texture as it is now....
