Although I do like this, on my monitor it suffer from pretty severe banding artefacts in the sky. Although some people claim to like the look - I think they always detract from an image.
Simple but effective, although I wish the corn was more defined. I find the mere hint of what i take to be hills on the horizon somewhat distracting as there is not enough to make out, but sufficient to draw the eye.
I like the composition and the use of portrait orientation, but your editing has let you down a little bit. On my monitor I can see a lot of banding/artifacting in the sky and several dust bunnies. You can clone/heal dust bunnies in basic, by the way (and that's the only spot editing allowed - just make sure they are dust bunnies!)
