This is a really amazing horse. Adorable! But the image might have been a little more effective if you had given him some "head room"(moved the camera more to the right). Great image though. Good work!
A little more head room might have been nice but your composition and how you have captured the shadows on the subject more than make up for a different view.. besides you would have lost that cool fence post on the left.. Nice color too.. well done...=D
