Well, I did a bit of editing to the lighting, since a lot of places have light on them that in actuality are blocked by walls and other structures of the house.
And then I really got to the root of the problem in that your house has no perspective on it. Since we're viewing the object at an angle, you need to be using 2 point perspective.
You can get away with a lot of fudging of the perspective, since an old sagging house won't have a lot of perfectly parallel planes.
Just have a couple of converging lines and it should become much more readable.

I was really lazy and didn't measure out my perspective lines at all. Don't follow my example, shame on me.
As for the overall composition, I think a couple of small figures standing by the tree is all you would need to put a bit of interest in that space. They don't even have to be well defined, just something interesting to find and look at over there.
