If the first photo was taken on level ground, then she is marked camped under. If you were to bring her back legs back 'til the canon bone was in a vertical alignment, it would be well behind the back edge of her butt, AND, she would become even more downhill. That is her major fault.
She also has tiny feet but they do look good and hard and I've ridden a little paint mare like her and she was a total fiend for hard work, but needed to be shod all the time.
Her coupling is also a bit tucked in ( much narrower in the body where it connects to her hind end compared to the middle of her barrel.) this means less abdominal muscle for that "lift" of the back for self carriage.
She ahs good shoulders and neck tie in, but as said above, neck is thin and a bit weak. Groceries and work.
Cute mare and probably a lot of fun to ride.
