Wow, those look great finished!
I admit to doubts at some of your WiP shots - I was thinking the pieces would turn out to look really "game-y", but painted and finished they look far more realistic than I thought they would, and obviously still playable!
The flexiblity appeals too, and I have to second a comment on the other thread - put them closer together to create a gorge, and built a rope-bridge to span the gap!
