Here are some more pieces from one of the Dungeons & Lasers sets I Kickstarted. These are the reinforced walls of a mine. I used several techniques for these, starting with a coat of black primer, followed by light coats of dark brown for the wood and grey for the stone. Then, I drybrushed the wood with lighter brown and lighter grey to create highlights for the wood and stone. After that, I applied a variety of different colours to a few random rocks to suggest various ores. Finally, I applied a brown shade to the wood and a black shade to the rocks.
