Doesn't stand out to me - The grass is pretty noisy, perhaps you cropped the photo a lot.
It also feels very flat - you were probably standing on a hill, but I think I'd have liked the picture better if there were a bit of horizon or trees in the background, something to give them placement in their world.
I wish I could have gotten a better shot. It was taken as I was driving and I had to shoot across my vehicle and out the passenger window. There was a lot of cropping because the show was basically framed by my Jeep's window. I had to shoot quick because chances of seeing three horses in a row like that is pretty uncommon I would think.
