Hah you've made more houses than I did
I personally really like how the colors of each element of the house match to each other (is this make any sense at all ? ;p).
But from close ups on your blog I can say that wood beams need more work. It lack of big details that cloud be seen, and those make it look bit flat.
I have an technical question.
How do you judged scale of you houses. I mean really. When I'm making this type of architecture, I'm always doing it with real-world scale and my buildings in game looks huge.. I mean they are realistic in terms of size, but I'm not so sure if that good from game perspective. And when I make smaller I start to think about "god damn, how those people can live is such small building, it feels smaller than my room".
On other hand, my real-world scale are to small anyway to make interiors (i tried and from inside it feels to small, especially with 3rd person cam).
