I've been wanting a cave for my Orcs for some time. I was going to make one out of Crayola Magic Model Clay but decided the better of it. I found a resin aquarium piece on eBay for a reasonable price and decided to go for it. The piece was not in the greatest shape. I added a couple of rocks and gave it a coat of gray paint. When it dried, I gave it a wash with some brownish-black paint. I went back in and dry brushed it with a grayish-tan color. I clear-coated it with a matte spray. I love the way it turned out.
Here is the final product staged with a Hydra figure I bought at Target years ago. The Greek soldiers fighting it are from the Heroscape Sacred Band unit. Take a gander. Hope you like it.
