A preset file, namely Canyon and Rock Surface Pack by TU from NWDA was used here to create this image and was originally created by Martin Huisman, aka 'Tangled- Universe'. I highly recommend you try it. The possibilities are endless; and, you'll have many options to exercise your own creativity.
The plant used is from Walli's Dry Shrubs; specifically, the '09' variety.
I want to thank TU for his help answering questions I had along the way. I've learned some things I was not aware of.
