From my point of view I think that the BO was envious
. The horse is just adorable.
From the pictures she seems to be a bit under herself in the front. In the first picture she seems to be coon footed a bit but it can be because of the snow, I can say exactly. And she has short neck and she may be downhill.
But surely she hasn't awful conformation as you were told. I think that she is beautiful, love her mane and face.
