The Throne of Stone
The smartest thing would be to make the whole thing over again in four sections; a cube for the seat, one for the back, and one for each arm. That way it's easier to paint the rocks around the corners because just like taking apart a cardboard box, parts of those arms can be one continuous surface and the long ugly seams can go on the bottom and the back :D
On the other hand, since it is one glorified cube, the whole thing without a painted map is like 20kb. It renders in an eyeblink (if you blink slow).
