AxeMan, with respect, I disagree with the suggested composition you posted.
I don't think stacking the line of horizon in the middle of the frame adds anything to the composition. I prefer Stangman's original choice of favoring sky over land in proportions. I like the blue portion of the sky starting from the upper right corner, and leading straight to the subject, i.e., the tractor.
Also, I find that there is enough space in front of the tractor to indicate direction.
I find the 2nd photo to have a few unresolved tensions in its composition: (please tell me if I exaggerate)
Mainly it has a skew horizon and lacks subject. It's a nice photo, but without a single subject, I would have focused more on texture and the repetitive pattern of the grass with an ultra wide angle lens shot at knee level. My line of horizon would have been placed in the upper 3rd section of the horizontal frame, showing less of this pure uninterrupted blue sky.
