As themackpack said, it's difficult to judge from these pics, however, I can tell you what I see right now.
His back is a tad long, which doesn't seem too uncommon for thoroughbreds, to be honest. I like what I can see of his shoulder angle...a lot. His neck looks like it could use some better muscle...either that or it's just built wonky to begin with. In one pic (the first one without the blanket) it looks like it ties into his chest too low, but in the next pic it looks pretty decent, so better shots would help determine exactly how is neck ties in. Can't really comment on his legs too much, except to say that in the first two pics where you can actually SEE his legs (the ones without his blanket on), he seems to be standing VERY base-wide in the back, with his hind legs almost splayed. Again, better confo pics will determine exactly what the case is there. His pasterns look upright in the second pic, but pretty decent in the first, so again, better pics are needed. I do like his head (although in the first two pics with his blanket on, he looks A LOT a QH gelding one of my friends used to own lol).
He does look like he needs a few more groceries. If you can see ribs in every single pic, regardless of the angle or lighting, he needs more groceries. "He's a OTTB" isn't an excuse and is likely to get you jumped on around here (not by me, just saying in general).
He is a very typey thoroughbred, isn't he? Those long, lean racer lines make him look like he could be in an old painting of race horses.
As a side note...I always chuckle when I see your screen name. Why? Because I invariably read it "Not Fart Of All." No idea why. Just the way my crazy brain works.
