I would think that the map would be larger in pixels than this original because it is very small. Its just a guide. I am like you in that my style is for a realistic view like a satellite image so that the towns would be really small in scale. If the map was 1000 pixels square then a pixel would be about 530 ft. So a village is just a pixel or two, a big town maybe 5. I think the expectation is to make a map that describes the locations as opposed to a photo real version of the terrain.
