From the confo shot, she is hip high, her neck is set quite high (which can make her naturally 'high headed'), and she is cowhocked, from what I can tell from the other shots. her front pasterns have a bit steeper angle than her rears, which could become a source of pain for her later on. She is a bit higher hocked than I like, as well, but not majorly; a low hock helps a horse more naturally drive from behind).
I do like how 'compact' she seems, and she has a decent shoulder, and she is decently muscled. She has a pretty gentle expression, and she could likely do pretty well in just about anything with the right training and exercise to build her up and help her be stronger. from your avatar, she has a HUGE hip!
I will take a stab and geuss she is either a barrel horse, or a roping horse...
