A better picture is needed to evaluate his hind end. As much as he’s “holding himself” and standing under, there’s not way to evaluate almost anything back there, including the angle of those legs
His front end is good. Not great, but good.
Pillar of support - line drawn vertically through the crease in the forearm muscle - is in front of the withers (good) but not by a lot. It comes down around the back 1/4 of his foot, which is good but it only does that because of more upright pasterns. They’re long enough that the uprightness doesn’t bother me much Ideally you want the PoS to be well in front of the withers. The closer they are, the more front-heavy the horse.
Lumbo-sacral (LS) gap - looks to be where it should be, which is right over the point of the hips. That’s one thing that doesn’t change based on stance because of how the skeleton is
Neck tie-in - it’s good, above the point of the shoulder, coming relatively out of the top of the withers, with a very typical TB dip there but not as pronounced as many. He has a 2yo neck still, on his 3yo body, not uncommon. Length is good
His shoulder slope is quite steep, right at the edge of what’s functional. The angle - scapula with humerus - is nice and open so that mitigates the straightness of the shoulder a bit. My guess is he’ll be pretty tidy with his front end over fences, as the straighter shoulder has room to rotate back to move the forelegs forward, and the > 90* angle (best I can tell) of the scapula/humerus will allow the legs to fold well
His back is nice, not too compact, not long at all.
I suspect he’s got a pretty nice hind end, but he has to be standing with the near cannon bone vertical to see what’s what
I wouldn’t kick him out of my barn
