He has a decent hinquarter and hind leg. Hocks are large and roomy albeit a bit high. His couple is rough and his back a bit weak and long. He has a nice wide chest and hsi front legs look good, although from this angle he looks a bit bench knee'd.
He stands fairly level.. and with trotting up hills and caveletti work, he will gain strength in his belly and get his "ring of muscles" working which will help him to support his weak coupling. His neck set appears goo and his shoulder lays nicely but the angle at point of shoulder is a bit closed. He will likely jump flat and safe with level knees (if you jump him), making him a good equitation jumper.
He is over all balanced and nothing stands out as being glaringly poor or overly stellar. He is a nice horse.
