Wow, those are some of the most amazing dioramas I've ever seen. But because of the larger scale of the figures, the dioramas themselves cover a smaller "area". What I'm working on is an entire Roman city in Gaul, in 1/72 scale. Aqueducts, a resevoir, villas and domuses (houses), temple, civic building, amphitheatre and gladiator quarters, a fort w/ barracks, docks, a trireme, etc lol. So even though it is 1/72, it'll still be a huge diorama. I even want to have some road-building, and a quarry. This should be fun.
Oh yeah, thanks to those who replied. Since this is mostly a 20th century and higher forum, does anyone know of one that would be able to help me a bit more? I still love these, I've learned a lot about the terrain building (water, trees, etc) from searching around these boards.
