I agree with kacey...mostly. I think that the cliffs do look good like this, although the edges of each cliff look quite sharp. You'd think a fairly soft stone like limestone would have eroded into a rounder kind of ledge.

Regarding the trees, I think Kacey's point about having trees above the bottom of the cliff makes some sense. Think of it like this: the first ledge is, say, 15 metres high. Whereas some of those trees adjacent to the ledge might be 20 metres high. Therefore you'd expect them to overlap the cliff edges a bit (although I can see how that might be hard to depict). Also, it might help to show more than just trees growing on the cliffs: what about vines, moss, algae, grasses...
