Great crispness in the wheat but the aspect of "space" is a little hindered in showing by the centred horizon. Usually a very high horizon in a photo represents "vastness" and "space".
But that is what a photo should try to do: bring home the feelings that the author wants to express in his picture to the viewer. And some of the old rules for all kinds of images, photos, canvasses etc. apply ... one of which is: a high horizon represents vastness of the country. A low horizon the hugeness of the sky.
Great shot, I would crop a little off the right to remove that distant electrical pole.. But great DoF and composition!
