I know when you post pictures you will hear a lot of negative, but I SEE a lot of negative in this mare. First of all, she is ridden in a tie down and the muscle development and braciness that has already been developed will need months of correct riding to remedy.
Her back feet angles are not good. She has very low heels, especially on her right rear, and I think this as affecxting her whole rear leg. She has too much pull on those tendons, and so she stands a bit camped under in some of the photos.
This looks like a tense horse that may have a lot of painful places in her body.
