Wow, he has grown into himself really nicely. I really like him, he looks like he'd be a great horse for just about anything.
His neck ties in beautifully, IMHO, and his neck is really nice. His head makes it look shorter than it really is because his head is a bit large and coarse. His shoulder is a little upright but his hip has wonderful angle. His hind legs are a little wonky, but it shouldn't cause any problems. He is what's commonly referred to as "coon footed", where the angles of his hooves don't match the angle of his pasterns. I don't feel you should worry about it, but I would keep an eye over the next few years to make sure that they don't start to drop lower.
His back is a very nice length and he's got good topline without sacrificing a good set of withers. He's a little bit downhill but nothing bad...and he's still young with some growing to do yet.
I agree, I'm glad to see that he grew into those ginormously long pasterns LOL. He has lovely short cannon bones and low set hocks. I imagine that he could have some very nice pleasure movement in there.
IMHO, there's nothing to dislike about him. You've got a winner there
