I like it, but 8 hours for isosurface with radiosity is not that slow.  

It looks a bit more like plaster(?) rather than stone, but the moss is
nice.  The grass looks a bit regular.  

Maybe some additional roughness for the surface of both moss and stone
would be good, but of couse that would slow down things
