I May not know much about photography, but this photo has a strong impact. Even though there are heavy shadows over both individuals in the photo, the detail of their faces and bodies are amazing. You can see the hard work expression on the man's face, the veins and muscles of his arms and the horse's face. The man appears serious and strong, yet one can see how gently he is holding the rein, guiding he horse. Also the color scheme. You have a dark green, compliment to the horse's ashy black, and then the red and white you creat a more contrast and stand out to bring more attention to the animal. There is also a mystery about this, his glasses do not allow you to see his emotion as well as one might like. Over all, great work.
