this is a very good shot and I can see why you thought this had so much potential. The light is beautiful, the texturea perfectly captured and the stone farm buildings really draw the eye. However in my opinion it could be even better with just a few adjustments in photoshop or whatever processing software you have.
Firstly I would crop the sky out completely. there is really not enough of it to make any impact and the real interest is in the fields. In this image the sky is just not adding anything to the overall image.
Secondly there are a couple of things cutting in to the bottom of the frame, A small grass hump and part of...something i cant identify. They are a little distracting. Rather than crop them out i would clone them out as I think losing any more off the bottom of the frame would lower the farm building in the image and its probably lower than ideal now.
If you want to play around further try cropping in from the top and RH side until the higher farm building is positioned approximately 1/3rd down and from the right in the frame. This is quite a big crop but hopefully your file size will take it.
I hope thats of some interest.
