Good feeling of "unexplored land" in this map, but the economic / strategic side is completely lacking.
For a taste of the lack of economic design, colonialists in Town earn gold by turning into boards the blocks from the stockpile (or bars from ores).
Forts are just training spots, far away from everything.
Natives just DM.
My suggestion is to think of a concept first for next map, then edit the rest according to it.
Right now, the only think we see happening in this map is an absolute DM, mostly focused around the town.
