The focus is going to hurt you here, a faster shutter speed would have done the trick. It seemed to be a pretty bright day, so you could have increased your ISO and set a faster shutter on TV mode instead of letting the camera choose your settings.
Otherwise - good shadow, colors and exposure. I would have cropped out the fence in the lowere portion of the picture.

Total Score = 3
The focus is a little out but the idea is good. It looks to me like this was taken over some distance....try getting a bit closer and using either a tripod or gently push the camera down into a support to prevent shake.
Too out of focus. Subject is a bit uninspired. The green field distracts a bit. A shorter shutter speed would definitely improve this shot, but maybe a different point of view even more.
