His shoulder doesn't look terrible to me, but in combination with his tied in knees, could result in pretty bad strain to the knees and lower legs. His back hind hooves look a little upright, but that can usually be corrected through trimming. Other than that, he looks pretty good to me.
I've never had any soundness issues with him, but I can see what you're saying about the tied in knee. I'll have to take a look at him when I get home in a couple of weeks, it may be just some oddity with the photo because the leg closest to the camera doesn't appear that way, but the one in the back does.
