Yes, I must agree with the quality of the photo. If you want us to give our true opinion of the horse, we would need to see him in his most suitable angle, which this isn't.
But anyways, maybe this is just the angle, but I was thinking that the croup was quite high for the breed. I also agree with the back looking short. But other than that, which I can't really say is a sure thing or not because of the photo, I'd say you have yourself one gorgeous horse!! His legs and neck are just wonderful, even if he is standing kinda funny!! Ha!
Don't flatter yourself, cowboy, I was looking at your horse
