Sjefen's photogrammetry looked like too much fun, so I decided to give it a try. Rock is photogrammetry, processed in 3D Zephyr. PAQ and Walli grass, other plants from Xfrog. Rene's moss in the close up. I think it turned out pretty well, though I scaled the rock up a little too much. Need to find a bigger rock :)

Looks nice. I like the close view onto the moss.
I like it. You're right about the rock size; a little smaller would give it more detail. I do think the flowers are a bit too uniform, maybe add some world PF for dirt/rot/color variation?
This does look nice, the rock turned out well imo. I imagine this is Standard Render? I notice some translucency doesn't seem to match up like on the moss. I think PT would handle that better?
Here's the second one with PT.
