this is what i would do.
make an electric fence, put the sun behind you and let him walk halter free along the fence. that way his ears don't shade his face, you don't have those pretty yellow bars interfering with anything, and you can get a larger focal length lens to blur out the background a little bit.
you can easily edit out the fence.
when animals are walking, it's a lot easier to get the classic near side legs further apart. also, the ground dropping away like that is kind of distracting.
take the photos around 10 am. the lighting will be a little softer.
also, if you went to the trouble of clipping him and he's tame, just take a quick swipe at his side hair to take out the wrinkles.
make sure his shadow doesn't intersect with his underline, it detracts from his profile.
did you use a flash? his quarter is a little bleached due to light meter readings. if you are standing more than 10 feet away, consider an external flash or get a good light on an extension cord.
