I found a little time today to make some progress on this map.
I added a 30% opacity grungy cloud layer to the buildings. If anyone thinks it adds to the atmosphere of the map, let me know. Also played around with the coastline.
Might put a tent market or faiground in somewhere?
Still considering a numbered or grid referenced legend. I worked out the population to be 21,600 or so. So that's a lot of places of interest to put in.
