Imo he has a bit of "two horse syndrome", it doesn't look nearly as bad in the second picture, but from his shoulder up looks like one horse and behind that looks like a different one. I'd work on getting his hind end muscled up, because it looks weak in comparison the the neck.
Overall, I like his shoulder angle and his legs look clean, his neck is just a little short which probably what is making the two horse syndrome.
Also imo, he is a bit too porky in the second picture and looks much too stocky for my liking. I almost prefer his weight in the first picture, but the best weight would be in between the two.
I'd love to see pictures of him moving he looks like he would be a very nice leggy dressage horse. Who is the sire? (I'm assuming that's the hano)
