Hmm. Well she constantly stands, almost parked out. Unless she has been trained to do this, it tells me she has some kind of a problem or is possibly in pain somewhere. If she were not parked out behind, she'd be very bum-high. She toes out in all four feet. She is very downhill. She is also back at the knee. Her neck lacks a whole lot of muscle and is set on high. She has a sharp wither, which would look better if her neck were improved. Her hoofs do need to be left longer at the toe. Her head is a bit large for her body, but wouldn't look so bad if she had a decent neck. Her forearm is short, compared to her canons. She also lacks muscle in the rear.
I find her definitely not breeding quality, as is borne out by the foal she already produced. I'd like to see that foal as he grows. He did look a bit odd to me, although foals can change a lot. She has a sweet face and a kind eye. Pretty colour too.
