In general, your progress is impressive;
The third shot looks best, whatever you did there. Could add some fine ground cover in some flatter spots to look like moss/grass growing out of cracks, could also add a little pulverized dirt or talus/rocks at the base to look like sediment/erosion/; adding a few clumps of brush over the ground cover between the rocks and maybe a couple at the base?
Also, will look better when some material covers the mesh. All in all don't expect it to look super until everything around it is in!
