This is dope, and I'm the first one to comment so I feel special. My initial suggestion is to vary the crack thickness on the rocks, mostly the big one on the left. A lot of the cracks (especially when zoomed out at a thumbnail scale) seem to be the same thickness.
Nice atmosphere and Super cool world!! I'd love to explore this place and climb around! The rocks are well done too :) I think the biggest thing I'm seeing is the rock on the left closest to the border. It's competing with the one in front of it. The shape is almost exactly the same and the size isn't much different either. I think it would look better if it was smaller and maybe a little different in shape rather than a smaller version of the big one :)
I like the colors and the painterly texture on this! I think you've painted it well - the suggestion I would give would be to, as was mentioned above, mess with the rock shapes a little bit more. I think they might be too similar to one another. Mainly the one on the far left, but also the background formations in the center/right. I think if you bow them more and chop up the range a little bit they differ from each other a bit more. You could probably just use the liquefy tool to push things around real quick and see if it looks cool or not. Shape variation in landscapes is always tricky and annoying!
