Finally finished! Terrain has never really been my strong point, so this project was a bit of a challenge for me. Pretty pleased with the results:
Sacrificial Altar - my first time working with insulation foam, so the edges didn't come out as nicely sloped as I'd hoped. The altar itself went well though. Cthulhu statues are repaints from the Fantasy Flight Bag o' Cthulhu, altar plinth is a 40mm base.
Graveyard - odd that my least inspired piece seems to be the one that came out the best. Uncle Mike's tombstones, and finally a use for my classic West End Figures Books of the Dead!
Abandoned Mine - this one took two tries, as my first design fell completely flat. Simpler turned out to be better.
