Nice short back and a decent shoulder. Won't say much on her neck set, since she is holding it rather high in the photo.
A little high in the wither, but typical of a TB.
Cannon bones and pasterns are long in the front legs.
Beautiful hindquarters, though it's hard to say about her hind legs. They appear as though they would be sickled, were she standing straight.
Neck could use muscling to match her back end and girth could be deeper but overall a nice mare.
