Hi! Perform this diorama for a good friend of mine. I wanted a throne for Odin and Loki. Styrofoam take as base material 2 cm thick, with a soldering pencil make the furrows of the stones, once completed, apply fillings with a brush to give texture of rock. neutral gray paint as a base, then apply dark gray brush diluted in water to achieve the uneven tone of the rock (do not apply evenly, but trying to make slight furrows and gaps darker) columns are made corrugated cardboard, and to use regular.el caulk lines throne is made of polifan, to give an appearance of the rest worked more rock.
