Love how you composed this shot for it is very interesting. The eye is drawn in first by the lovely greens in this land of green. It is then that our eye spots the single white horse that occupies the space. Love the title for that horse does look like she/he is contemplating leaping over the fence to get the greener grass. I also like how the fence acts as a leading line that serves to break up the image into two halves: the 'greener' side and the side with the horse in it.
This is terrific. I love the leading line of the fence and how it divides the shot as well. The green tones are so rich and soothing. Gotta love that single white horse too! This is my kind of shot.
