Two things I would suggest: 1. Though you cannot see the roof of the house in the picture very well, I think it needs some more detail. Maybe use som fences or put some more depth in it. 2. Your wooden pillars look very ... ehm, angular. Can't describe it really, but they are pushing themselves too much to the fore(which means: first reaction of a player: looks at pillars, thinks: uhhh. Second reaction: looks at detail, hhmm, nice :D.) That's what I would suggest to change, but it's seriously already a cool nordic house . Good luck on it futhermore. P.S.: Have another small hint for your pillars Little Pillar Hint You can try to use the left variant instead of the right one, because then you have more space for your interior ;)
Looks pretty nice I've got 3 small pointers though (not including the ones mentioned above me of course) 1. Perhaps some item frames over the buttons placed on the ends of the logs? 2. On your second level the wooden planks are hiding a lot of the white wool, this creates an overall dark feeling. 3. Lighting on the building itself might be nice aswell?
I would try thinning out the roofs edges. To me, it looks like its really thick compared to the size of the building. It could be too heavy and crush the house Functionality has been on my mind lately :o
