Actually, she is not a bad horse at all. In the first image she looks a bit back at the knee and she is a bit long in the back and a bit rough coupled. Her shoulder is a bit upright but the angle at the point of shoulder is nice and open and the angle from point of shoulder to elbow is very nearly perfect. She might look quit nice over hunter fences.. but the appearance of being a bit back at the knee in front would have me keepint the fences below 3'.
Her hocks are nice and low and the entire hind leg is very very nice for the breed.
When you get her "ring of muscles" working for her with training and foundation work, she should be a very nice ride.
Drafty and elana beat me to it (as usual! ;) ), agree with both of them. The knees are the most concerning and I think what drafty was seeing in the loin was the weak coupling which elana pointed out. That can be improved with diligent work. Overall I like her very much, more strong suits than negative. What are the plans for her?
