LOL, I would say it cost a ton of sleep....
You have loads of detail, and excellent shading techniques, which to me is really difficult with a mono-tone drawing. The architecture is really intriguing and looks to have been influenced by a couple different styles as well... Many structures like that often end up becoming part of the locals houses. A stone here, a cornerblock there, a rock walkway, until much of the old structure is missing.
Thank you very much for your words, if you are right many old constructions have been razed by the people of the places and have lost many pieces, is in particular is preserved about 100 meters more or less the rest is what I have commented has disappeared. Thanks for going through my post.
