That is really impressive looking!

from the Amera site, I never took those buildings to be just the facings. I had assumed they existed from a front and a rear moulding, so you could join the two together. But instead, you had to fill the front half...
Hmm, even though the amera offerings are pretty cheap, that does limit their usefulness somewhat. :\
Still; you did a cracking job and the inside of the walls now look even better than the outside and the end result is really convincing. The foliage especially really works.
Great job!
