Wow. Well I don't consider conformation critique as pulling apart or bashing a horse. So maybe that is the difference between how you see it and how I see it. But please realize that there are people here, including myself, who don't know the rules and maybe it would be in better taste to kindly explain them. I don't believe the original posters had the intention of being mean or bashing someone's horse and I know for certain I sure didn't.
And ears are very relevant on the Arab. This is from the Purebred Arabian Standard of Excellence manual...
The head is a distinctive feature of the Arabian breed. It should be short with a broad forehead and deep circular jowls set wide apart, and tapers to a small, refined muzzle. The ears are short, pricked and alert with fine edges and well defined tips curved delicately inwards.
The op stated that this was for practice for horse judging so one should judge based off the standard. I've judged Arab halter classes back in the day, so that is where I was coming from. It has nothing to do with personal prejudice but breed standard.
