Very nicely balanced image with lovely colours. However, I think the image would be even stronger if you cloned out the 1/2 in 1/2 out little bale in the lower right corner and then cropped up just enough to eliminate the dark line of earth at the bottom of the image. That bottom bit distracts us from the lovely rest of the image.
Great sky! I also love the wonderful greens in front. My only concern is the tree looks like it has a little bit of a halo around it. Still very nice image.
Love the colors ... you might want to turn the sharpening down, especially around the tree. What I usually do is sharpen the whole picture, then use the History Brush to undo the sharpening around the edges that become too sharp.
