First map: Too much water. But it's meant to be large, it's ok but add more trees around it because it kinda looks empty.
Second one: Nice one, but you used the blankets wrong unless you want long beds. It kinda looks awkward this way, though. Also add more stuff to the walls, as they seem to be kinda empty.
Third one: More trees, more trees, please. :P And those stairs don't really fit at all, you should use the default mountain ones. And as for the paths, it doesn't look really nice how some are really thin and some are very fat.
But overall, nice. ^^
