Modular Cliff Rock

In order to create this cliff, I made a straightforward cubic rock. After that I duplicated the rock a few times, rotated it, and scale it until I got the shape I wanted, then I started to sculpt the large bodies with a trim smooth border, clay bump and Orb Flatten from Michael Vicente, all of them with square alpha. For the small details I used some noise brushes, but I could also do that in Substance Painter.
All in all, I am pretty happy with the result.
