She's lovely, over all, and fairly well balanced.
She is cowhocked, and toed out in the backend ...even without a rear shot, that is actually fairly obvious by her stance.
She is a bit long backed, and has a shorter rounded croup, rather than a nice slope. That's probably in part of her Arab side, though, and certainly isn't a life threatening or career threatening in any way. Her hocks are set pretty high as well, now that could make it really hard for her to collect, especially because she's already hip high.
She has a decent shoulder and neck, although her throatlatch is a bit thick; that could be helped some with a lot of bending exercises mainly to help her become supple; even a horse with a thick throatlatch can be supple, it's just a matter of 'training' those muscles. Neck sweats can help some too.
Over all, I think she's a really cute little horse, and she should do fairly well in what ever you choose.
