Taste will always be an individual thing. Still, thank you very much for your input and I tried to change what I thought would improve the map.
Yes, Vers.0 was too light, Vers.1 too dark but with the roofs too red, I like Vers.2 quite a lot but instead of green fields and woods I should have drawn barren trees and snow covered fields and finally Ver.3 would be more fitting a setting in an arid part of a country like Arizona or southern parts of Italy or Spain.
So here we go with a darker version than #0 but with roofs desaturated to resemble more regular roof-tile.

PS.: The river is green because that was always my favorite color and I have seen enough "Blue Danube's" in various maps....and then there was the algae bloom
