Dundjinni is mapmaking software specializing in photorealistic maps, especially for "tile" miniature maps. I can recommend that program, for I used it for about a year & was very happy with it. Here's their main site:

But whether you use it or not, make sure to visit the Dundjinni user forums: it's treasure trove of downloadable objects, from floor textures to statues to trees to.... It's even searchable for your specific needs. I believe you can use its objects in CC3, and I know you can in art programs such as Photoshop.
