OMG That buckskin (?) paint is BAH UTIFUL! Not that your horse isn't, she's a pretty girl. What I can see (still learning) is that she is downhill and post legged in the hind. But others can correct me if I'm wrong.
She is pretty, especially her head, which is her nicest feature. She has a very long hip (croup) and is post legged with rather upright pasturns all around. She is square both front and back and has a nice neck, which ties in nicely at the wither area. Back length looks good, yes, downhill, but most Paints are.
Not exceptional horse, but overall a pretty good looking mare with the sweetest face!
