I am quite fascinated by your first photo here, and I like the stark shadows and contrasts in that one, and I like the b+w, and I really like the composition of that one. The horses look like "twins" or like they were taking part in some "synchronised" something-competition ... that is a funny aspect to the photo. And in that same "synchronised" manner the light is on one side of their faces only, and the shadow on the neck of the far horse helps to enhance the face of the near one ... there is nothing about that photo that I don't like. Even your lover POV (point of view) appeals to me!
