That is just so much better. Well done.
Just to be nitpicky, Bottom ledge in the centre - I wouldn't have the cliff edge tile on the right where it butts up against the main cliff. Ledge one layer up on the right next to the most rightward ladder, have the last tile on the return without the cliff edge, just to emphasise that the bit with the ladder protrudes from rest. The ledge above that ladder, no cliff edge for that section where it butts up against the other pillar. If my eyes do not deceive me, the pillar that it is abutting has a straight tile. It needs to be curved to match its top.
A more complicated one to explain is in the middle, the one where there are 2 ladders going up to it. Trace along the right side of that ledge. You have cut it in to the main cliff, and then on the right there is a bit that looks like it comes back out again from the main cliff - but the top edge of that bit of main cliff is straight; there is no outward curve. Furthermore, although that 'sticking out bit' is theoretically one tile longer (going downwards) the next mini ledge is at the same height as the one I've just been talking about. Or is it? It's very difficult to work out the relative heights of things. Don't know if I will have time to do a quick edit, so you may have to rely just on this verbal description of the problem.
[Edit on that description - part of the problem with that little collection of ledges is that the one with the ladder is 3 tiles high, and the one next to it is 2 tiles high, but they both end at the same level at the top.]
For shadows, I would leave the very last bit at the top without shadow. As the shadow pen is half a tile, that means that you just leave off the last half tile.
I think if you compare this last map with your first you will appreciate just how far you have come with it.
