I would agree that the sky is a bit oversaturated, but I'm not having any problem at all with the grass/wheat, or whatever the crop is in the foreground. That's not an unusual look this time of year, and in the evening light...at least on my monitor here at work. (Which, admittedly, isn't the absolute best.)
What I would change, though, is the perspective or the cropping of the photo to get the horizon out of dead center, and to get something of visual interest into the foreground. Then you'd have a stunner!
