Essentially, what do you want this photo to be about? The sky? The field? The distant hills? The house and its surroundings?
If it's the house and its surroundings, then you've got to get some separation between the house and the hills--boost the blacks and shadows in raw and bring back some detail in the hills. Make the house "pop" a little.
I can't tell what that lighter strip is at the top of the hill, but I would try darkening that or cloning it out entirely as it draws my eye there.
Also, assuming again it's the house and its surroundings that are important to you, try a crop along the lines of 6x12 or 6x17 and then darken the sky to simulate a graduated ND filter.
And desaturate those orange tufts of grass in the field. My eye goes right to them.
From there, I would dodge and burn as necessary and experiment with a light vignette.
