I carved the floor back wall and idol wall from foam board and pressed all of the detailing in by hand with a ballpoint. Next I bashed the hell out of each section with a lump of broken paving stone to add texture and fixed the parts together. I painted the whole thing flat black then dry brushed it to within an inch of its life with many shades of gray, then I painted the spiders and fixed them on and added a little lichen. hope you like it .
