Best practices: The desired effect is to differentiate individual specimens. Notice how the waterline rocks are distinct and don’t sit flush with one another.
Best practices: Rock formations evolve over time and the most realistic non-natural installations reflect this. Here, a large piece appears to have split from the main formation and fallen to the ground.
Common mistakes: This formation contains mostly similarly sized rocks and has a stacked, rather than natural appearance.
Common mistakes: Here, there is very little differentiation, and protruding, rounded shapes don’t appear in nature.
