Not a bad looking fellow overall. Right now he is very downhill, which he might level out from some he most likely will never be level. He also likes to stand like he is sickle hocked, however I am not sure if that is his structure, or just the way he is standing in these photos. He has a nice length of neck, rather large head, shoulder is a bit upright (though better photos may reveal otherwise), back is fairly short with average coupling. Hip is on the shorter side. Pasterns show adequate slope and good length. Good substance of bone. Feet need attention.
Looks like a versatile using type as he matures. Shows much more stock horse type than Arab (would never have guessed he was half Arab).
Better photos may reveal some of what I have said is not quite accurate.
