Minor input: I feel like it'd look better if either the top left part of the cliff were brought in to the right one tile, or (IMO a better option) if the bottom left part of the cliff were brought out by one tile.
Basically, so that the ledge doesn't cut off to exactly the same column.
Of course, if it's literally been hacked away by some gigantic blade or something, then the current look fits best. Though for that, it'd have to be something that makes a clean slice like a blade or a beam of some sort. An arm or crashing monstrosity wouldn't leave such an even clip.
