Yeah, it's kind of a stylistic choice I guess. I don't need EVERYTHING to pop out... just the stuff that feels like it should. Compared to other things, I don't see towns as being that tall.
Flat stuff:
Towns
Docks
Forests
Mountains (lower elevation)
Jagged rocks in the water
Things that stick out:
Castles
Towers
Mountain peaks
Cacti
Palm trees
Misc trees (there's a large tree in the gloomshade forest)
Tall things
etc
