Eh, I just kind of 'updated' the default Graal chimney's, which were already vertical.

As for cliffs failing to show depth... I honestly don't know what you mean there.
They have to be tileable, thus they can't really be darker at the bottom and lighter at the top(which I'm assuming is what you're wanting). Otherwise, I think they go back more towards Zelda's style of depth, in which the cliffs look much more like objects rather than flat surfaces, due to the way the darken as you go around.
