Moonlight Rock Under the Sea

Being I love to  incorporate natural stones in my art, I couldn't resist when I found this  polished Brazilian Agate geode. The moment I looked at it, I knew how I was going to create a beautiful ocean scene around this stone.  The stone is about 4-1/2 inches long and 2 1/2 inches high. It protrudes off the canvas, giving a 3D effect that is hard to capture with my little camera.
