Thanks for everyone's kind words

Terrific job. Like the castle wall - is this one resin?
It's that soft resin-ey stuff James. Slightly spungy. It's from Tablescape and part of their Middle Eastern/North African range. I originally bought them for the Indian Mutiny but I needed something to block out all my paints today and they were at hand

They're pre-painted, which I don't normally go in for but I think they've done a decent job so no modification needed. If anything I'd probably add them to a large base in sections of two or three bases then fill in the gaps between the single pieces with Milliput.
