The mare's front is very nice. She is tied in behind the knee. The issues start with her hind quarters. The entire pelvis is set back too far and is too steep creating a weak coupling. The femur is too short placing her stifle a bit high and the angle is too shallow due to the placement of her pelvis. This is coupled with a long tibia that goes to a nice, large hock that is over straight.
The placement of the pelvis and its angle force the entire hind leg to be placed too far to the rear and the lack of length of the femur and improper pelvic placement and angle create the posty hind leg.
I like her neck placement and her shoulder. She has a kind eye and a pretty head.
Remember, no horse is perfect. This horse is better than most. I do wish she had a stronger coupling and a different hind leg structure starting with the pelvis placement and angle.
