Is it my eyes or are they a bit soft? It looks a lovely area but lovely areas can be difficult to do justice to in an image. I know you can only work with what's there but the first could do with a 'lead in' towards the hills. The second would be much better with more hill above the horizon (but impossible, I know). The third I think is a much better composition as you naturally look over the wall to the sheep to the hills. Good sunshine and shadows as well. If it was me I'd definitely be going back as well. My feet are twitching just sitting here!
