Granted, I don't know a ton about Morgans so keep in mind that I'm judging her with an eye gauged for quarter horses
Her neck is set a bit higher than I like, but that's a Morgan thing. If you're aiming for a QH western pleasure headset with it really low and flat, you probably won't have much luck because she'll be incapable of carrying it there and using her body correctly. She's got a really nice shoulder; good slope and strong. Her back strikes me as being on the longer side of normal and her hindquarters are a little steep. She stands camped out on the back.
Her feet appear to be big and strong, but the first thing that popped out to me is that she's pretty light on bone in her legs. I'd be hesitant to try anything too stressful with her like jumping or competitive gaming (barrels, poles, etc), but they won't stop her from being a very nice little pleasure/trail mount. She also appears to be ever so slightly back at the knee. Again, that shouldn't
effect her long-term, but it's something to keep in mind.
If her temperament is exactly what you're looking for and her training is acceptable and will be what you're looking for after a tune-up, then I would keep her at the top of the list too.
As 2bigreds said, I'd keep looking at others too just in case a horse more perfect came along or in case she gets bought by someone else, but I like her a lot.
