+1!I think there is potential - I like old farm buildings.
Is there room to open up the shot a little? I don't think there is quite enough in the barn to make it the only item in the shot.
Right away the first thing I noticed is that you a) Either have the clarity slider pumped up way too high or b) have over sharpened it. The clouds look a little strange and there's haloing around the barn... most noticeably where the roof meets the sky.
