I had a gelding like this horse.. in fact, if you just made this horse a chestnut with a blaze and flaxen mane and tail they could be twins. Nice hind leg angles, a bit steep in the shoulder but decent neck set and high point of shoulder may help those things. A bit long and weak in the coupling area and a bit butt high.
That being said, she has a GREAT rear end engine and good bone.
This is a really good horse. She is not refined and not fancy but she has a lot of the right things in the right places and proportions.
