I'm talking about the complete flat ground in Bazaar, Mirage, River Delta v2, Quarry, apart from the quarry and Tilting at windmills.
Sure landscapes as in your pictures exist, but I doubt the fields were that flat in Medieval times. This whole road with planted trees doesn't scream Middle Ages. I think all of your maps would look better if they weren't so desperately flat. I get that it is convenient as a cavalryman and mapmaker, and I understand that there are flat landscapes. Hell, that first windmill picture you posted is my country, probably the flattest country in the world. Still the maps would look better and less artificial if they had a bit of terrain.
