Have you seen the article in the Sept. MR on using ceiling tile to model rock? I've done something similar using leftover scraps of homasote. I'm not all that happy with the painting, it needs some highlights, but I think it compares favorably with the photos in the article. The scene, as just about all of the scenes on my layout, is incomplete. I tend to flit from one area to another, never completing aone. No discipline. Well, who needs discipline in their hobby!
