My first suggestion would be the same as what @elianafranzenburg mentioned about placing the sheep on the right so they will be facing in toward the center of the photo. Also the background is a little distracting. The buildings beyond the trees distract from the subject and should be eliminated from the composition or sufficiently blurred so as not to be a distraction. The haystack makes a nice element and even the wooden structure has potential to add to the photo if composed more purposely and perhaps blurred slightly.
