Too many corpses, especially of different kinds. add some more ground mix on the cave ground to make it look less speeded. Also avoid 1sqm places where the borders stack up.
Less autoborder as well.
So summing it up: less autoborder, more thinking it through.
You don't think everything will burn up by that lava? Grass next to lava = fail every day.
looks a lot better, although you want to make the differing ground types as natural as possible (ie less blocky). also that bridge on the right is big too xD
your houses could also be split up into smaller segments with different rooms, so they're more realistic
I like it
City is very nice
