It was pretty fun to experiment with the texturing on the wall. Note the magician's robe, made with two capes.
The top level is probably the main focus. Note the cracked and bent stone around the creature's footsteps. The creature itself was a pretty challenging build, involving lots of hinges, SNOT, and minifigure hands.
I thought I commented on this . . . Oh well, I am now. The wall really impressed me; all the little details and textures; well done there. Then the monster's another thing; terrifically scary. We know who's advancing!
