Pics a bit dark but from what I can judge in those photos, she's a bit long in the back, long pasterns that rest at a sharp angle and her neck looks long as well (but that could just be the way she's standing). Also slightly sickle-hocked in the back legs.
I don't think her neck or back is too long but her neck,and throat latch are thick. Can't tell if she is sickle hocked since she is not squared up. Weight is a little heavy but I prefer that to too thin. She has a relaxed look to her. She could use some muscle.
Thanks you, she was only started this summer, but came up lame so has not bin worked much and before I got her she was nothing but a pasture horse. Her throte latch isnT all that thick I think its the winter fuzz, I will post a summer pic:)
I like a lot about her and I agree with another poster; her neck is fine....she's just out of condition and has a bunch of hair, that will account for what LOOKS like as a shorter neck. I'd like to see her fitted up and in a slick coat again for a fair confo analysis.
