Second: Mare C
This mare, when divided into three segments, is the most balanced of the three, and I would have placed her first if not for her hock angle in this photo. I believe her hind legs aren’t actually as sickle-hocked as they appear here, and that she’s standing with her hocks placed underneath her too far, but I have to judge her on the photo.
Her head is even more feminine than Mare A’s, and she’s trimmest in her throatlatch. Her neck ties into her chest the highest of these three for the best flexibility. She’s not as deep through the heartgirth as Mare A and doesn’t have as much definition in her withers. Her croup is also higher than her withers, but as with Mare A, not enough to be a major fault.
Structurally, she has more slope to her shoulders and hips than Mare A, and her shoulder and hip angles match well. She also has clean legs and good slope to her pasterns for a smooth, comfortable stride. I’d like to see more volume and definition to her muscling.
