Can't tell if he's camped out or if he's sickle hocked, but there's something going on back there.
His hind end looks disproportionately small to his more muscular/beefy front end.
His shoulder is decent, but his neck ties in a bit high on his chest for my liking. His neck also seems on the thin side. Interesting...before I even saw the pic of him in motion, I thought he looked like a horse that ran around with his head in the air...turns out I was right. Our trainer's arab gelding has the same look to him and his head is always in the air like that.
Can't tell if he's lacking in his topline or if he has shark fin withers, but those looks like some tall withers. Is he difficult to fit a saddle to?
His front legs look good and straight, which is nice, since I've noticed TBs tend to be a bit over at the knee.
He also has a rather flat croup. At least it looks like it in this pic: http://sphotos.xx.fbcdn.net/hphotos-...72994750_n.jpg
I like his sire, but they did kind of a crappy photoshop job on him, to be honest.
