I'm with Conan on this one, the terrain could be better. It is not bad, it is just so generalized. Refer to
THIS guide. I would recommend rampscaping for this build, but it is a personal choice.
I do enjoy the cabin's exterior, the drooping snow is clever and well done. The patio needs a bit more, it looks incomplete. The trees look nice, I think they are duped, but I can't tell for sure, which is a good thing.
Overall, 7.5/10
