Here are the walls, so far. I've built the 'skeletons' of them all now. Basically, there are enough straight pieces that, with the tower and gate, it's 5' (1.5 m) long, or, using the corner piece, it can cover a chunk of table about 4'6" x 18" (1.4 x 0.45 m). I'll need some buildings to go 'inside' the city, once I've done texturing and detailing the walls.
