Large hooves are usually healthy hooves! Give me large hooves over dinky hooves any day.
I don't much care for ewe necks either, although for my purpose (trail riding) I doubt it would be a huge deal.
I like I nice facial expression and attractive eyes on a horse, even though you really don't ride the head.
Pasterns, well, I really don't get excited about them one way or another unless they are too upright. I don't want a horse to ride like a jackhammer! Bad for their legs, not to mention my back. My mare probably has pasterns that slope a little too much, but I would rather have too much slope than too little. Ideally they would be somewhere in between.
It's funny this subject came up, because I was just talking about this to a friend the other day. About how beauty is in the eye of the beholder, and how often times what one person values in a horse isn't what another person values in a horse. For the most part, everyone can agree we want a sound, healthy horse, but what a person wants for showing may not be what we want for trails, and what a person wants for one discipline isn't desired in another. A horse can be practically perfect for one person's ideals, and another person wouldn't even consider it. Interesting to think about!
