Time for an update
I decided to go for a very basic drawing stile first to try different mountain locatios, vegetation, etc. What do you think?
* Currently the upper area shall be quite barren, but with farmland at the left before the mountainside
* The volcanic area is tropical
* The lower area provides much farmland
I`m really not sure, if the placement of the rivers or the farmland/barren/desert combo in the upper region makes sense.
