wow that immage looks like you havn't any modeling skill (nearly evrything is made of cubes and cylinders and the trees are firs with cherry blossoms or somethings like this) and after the modeling you had no more pleasure to texture properly (the gras is far too upscaled and I never saw a roof made of that kind of woodenplanks also I think there are no bump normal specular displacement maps and all that stuff)
Sorry I know that I'm not the best 3d designer and some of your works are very good but I don't understand why you got such a good score for THAT work.
