I think I would rather see more, or less of you ass. Either just a head and shoulder shot or the whole thing. For me, a little better lighting would have been nice too.
Not an ass, but here's a horse shot I took...
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.
