She's a really nice looking horse and well balanced for being part draft. The first 2 pictures made me really wonder about her legs, it looked like she had really thin bones, but I think it might have just been the shadows playing tricks.
Her back is just a touch long and she's long through the gaskins, which is making her stand camped out. Her head is a bit large and a little coarse (curse of the Percheron in her lines LOL). Her neck is short but it ties in well to her shoulders. Her shoulders have good angle and she's got a good set of withers on her. Her hip has good length, but it's a little steep. Her hind legs look good with good angle in her hocks. She might be a bit back at the knee but she's got good pastern angle and they appear to be a good length (hard to tell when you can't see her whole leg from the side...grass is in the way). Her feet are large and look solid, though there may be some flaring going on that the farrier should address.
All in all, a very nice young mare.
