Here's a small project that I've also delved into recently with making my own scenery. A small ruined rock wall overgrown with moss made from chunks of pink insulating foam. Specs are as thus: 4.5 inches long, 1 inch wide, and 1 inch tall. The green knight figure is presented along with it for comparison with a standard 25mm scale Heroic figure.
