A few things, first of all I can just view it of the perspective of a little modder, without much experience. Made some archtitecture models, though. Just here to help.
1 - why is the texture brighter at this point, looks weird for me.
2 - I have made quite good experiences with a darker part at the lower part of buildings, like dirt, more plants. I would recommend to add a level of "stairs" between the ground and the model. Houses normally just don't stuck in the ground.
More or less like here:
3 - I really like the roof, actually the whole wooden part. Maybe u can add more details somewhere or some more depth through normal maps, but it is actually quite good. Which shader do u use? I'm out of the game for a while and maybe it is just the engine, but the lighting looks quite odd for me.
In general, the level of details is quite low. In the model and the texture. Use more polys. Create more little stuff, like overhangs, corner stones, reliefs whatever, just make it interesting. Datails make a huge impact on the overall view.
Do you use ambient occlusion? The stairs would look better which more contrast, actually the whole model would in my opinion. More dirt and details everywhere, less repetitive textures.
