In this one the urban density is high, and the terrain is mountaneous. Not sure what's going on behind the mountain, looks very... dreamy.
This one takes place underground; A mining town, perhaps.
And here we have an island, with more of a medieval vibe. A castle sits imposingly up top and the coastline is heavily fortified. I like how the denser town at the docks is shaded by the buildings, presumably for lack of artificial lighting.
