He's high withered. Not a major problem, just makes saddle fitting a bit tricker. He looks a wee bit sickle-hocked, but it could just be how he's standing.

Looks straight shouldered, but not too big of a deal, fairly common in fact. He just won't make it in life as a peanut roller
I LOVE THAT NECK. It doesn't go straight into the chest (he actually has a chest! I love it!). Just need muscling, of course. His front legs look pretty clean, he doesn't seem to have upright pasterns. Overall, I like his topline and he has nice rump (IMO) for his build.
I think with more work, especially muscle-building exercises to work off that Buddha belly (mine have 'em too
) and build strength in the neck and hindquarters, he'll look better then ever.
Kudos for getting one off the track! He looks like he'll have a nice long career ahead of him :)
