Cliffs. Hell yes.
See, in Angels 22, there was water and ground, but never an actual transition between the two, like, say, a shoreline. I kind of dreaded trying because we're on a kind of tenuous 2D illusion, and I didn't want to call it out by making a clear "from the side" thing stuck on an ambiguous island. In retrospect, I think it turned out rather well. Up next is a beach beach (not just a cliff).
Goodnight!
