c.sam,
Thank you kindly. In photos 1, the rear of photo 2, and 4 I used rock molds and resin. The subterrain is insulation foam followed by plaster cloth. This process is much more involved, not only with pouring the resin and getting it out of the mold, but also with the coloring. With that being said, I prefer the end results. The key with coloring resin rock work is layers and patience. Those sections took me about 4-5 days of light washes of various colors. I used tans, browns, greys, and a bit of red. By the 3rd day you start to see things transforming.
Photos 2(front) and 3 were done with plaster of paris. I used insulation foam as the subterrain, followed by plaster cloth. After plaster was mixed and poured in manageable sections it was then picked, chiseled, notched, and molded into shape. Again, washes of various colors were used and then everything dry brushed using a cream color acrylic. The plaster method is much faster.
