A layer from JOSM is currently uploading which outlines the river systems and jungles of central Commonia. Its a big file and will take a while, and I don’t know how it will turn out yet; I’m expecting a few glitches, which I will sort out as soon as I can. The rivers are partly based on rivers that were already there, partly new, but I haven’t removed any rivers, only re-used previously drawn sections in slightly different ways, to make them a bit more logical - to me anyway. I have tried to base them on river patterns in the Amazon and Congo, while using what was already there. The jungle fits in between many of the river multi-polygons. Although there will be a lot of landuse=wood there will still be plenty of places for people to build in central Commonia.

As part of Luciano’s challenge (which I’ve already failed) I’ll also alter some of the 100s of km of straight-line roads in Commonia, as I check through the upload data, either replacing them with other forms of transport or making them more realistic by adding curves, etc.
