Shoulder is a bit upright
Appears to stand under himself
Back is borderline long but not bad
Bum high but on the plus side he does have a nice bum ;)
Just a tad posty in the back legs, but again, nothing severe to worry about
Gorgeous color too
Well, the picture isn't set up very well for judging his confo. I disagree that his back is long or that he is posty legged. Actually, he's well built to my eyes. His neck is a bit short, and that might give the illusion of a long back. And throatlatch is not super clean.
The angle of his front hooves seems a bit off. Like too flat?
I think he is a nice looking horse and when in condition , will be dandy!
