I'd say the roofs eave line is OK, it just need more pitch and a discernible ridgeline. The walls, on the other hand are way too precise and regular. These buildings were hand hewn. And beams are more massive than posts. In the last week or two I saw photos from the Hobbiton movie set in New Zealand. It's a great blend of asymmettry and big roofs -- thatch is thick Good luck.
