I'll give it a shot for you. He looks like he has low pasterns. A good trim will help that some, but I think he'd still be low. He looks to have underrun heels too, especially in the first picture. His back legs are a little too straight, and he has a touch of cow hock. He could use some muscle toning on the back end. Think hill work and impulsion. His legs look a bit short for his body in some of the shots, like Tulula said, but if you were higher than his back when taking the pictures, that could be an illusion. His front end is very nice. His neck ties in well, he has a nicely shaped head, and a kind eye. He does appear to be very solid, maybe not breeding quality, but definitely a very functional riding horse. None of his faults are glaring, and some good farrier work and muscle toning will go a long way toward improving the ones he has. He's very cute, I like him a lot.
