Brilliant stuff so far. I love the look of the first ruin. Getting that random appearance for the stone blocks is hard to acheieve. Yours look excellent.
This. Working with XPS masonry is a new technique to me. I have not quite mastered the texturing technique and the block seems so flimsy and unsubstantial when you build with them. But I find that white glue and glalc do wonders to fortify the foam. The pillars in my gallows are strengthened with threaded rods but they take also take quite some handling after being prepped with glalc.
Anyway, Codsticker has really mastered the material in this build. (Perhaps we should start a lodge of Free XPS masons?)
