Oooh pretty horse!
She seems to have a rather ugly neck, like it's too skinny compared to her head/body. In that photo, she is standing under herself, and her legs look posty. Her croup is really steep and she has prominant withers (which I actually prefer to nonexistant withers, lol).
Over all I think she's a well-made little horse, and I just love her color! I definitealy see "reiner" when I look at her! :)
Random, but her star matches the horse's in your avatar ;)
