Definitely my favorite playble-mapping mapper in the whole community, you map like a genious without overdetailing at all. Love your work and hope to see it in-OT eventually, would be an awesome experience to play on.
PS: I guess it's different for eveyone, but seeing your Rook~ mapping screens, I can see that you just start detail mapping from the begining, which is not wrong at all. Just, as a tip, maybe make the whole core/foundation of the city (the shape, the street/road system and housing etc) then lay on the detail after. That's what I do though, not everyone does it the same way.
