I like the first new treatment the best. I'd say stick with that idea and add some colour/texturing to those nice cracks you have going on.
I'd limit those cracks to sloped faces, though, to make it appear like fractured rock, maybe stick some grass or rocks on the flats, instead of the dried-mud-hills all over, and add some
small redirects on the X+Z's of the cracked surfaces.
Stick with No.1 and also, I'd reduce the 'haze glow amount' in your atmosphere, by about half, at least. It's very blown-out with white as it is.
The atmo
colours are great. Me likey!
