I decided to go with a granite look for Shannon's throne. That means a whole lot of stippling. It takes a while, and is going to ruin the brush I'm using. I picked a couple colors darker than the base and a couple lighter. Then, I stippled on each color, leaving some of the base showing through. That was a little too much, so I glazed over with the base color to knock the texture back down a little. Last was shading and highlighting, including the edges of the stone and the cracks that were sculpted in.
I have a ways to go on it yet. This part of the throne is almost done; I still have a couple areas to texture and that should do it. But the whole back of the thing needs to be textured, and then I have to do the inlays and decorations.
