Well... He got a little shorted on the overall balance department... As seems to often be the case with Draft/Stockhorse crosses (though there are some nice ones, many seem coarse looking, with large heads, small necks, longer backs and drafty pelvic angles)
In this guy's case... He has some years to fill out, so he will probably become more substantial as time goes on (this is often true of unworked drafts in general)... But, he got the draft head, a shorter draft neck (though he got a decent neckset ), I think his shoulder is - overall - decent... The photos make it hard to tell, but he's not overly steep, nor is he particularly closed in angle and the neckset he has should give him more range of motion than a lot of drafts get. He does seem to have a long back, long loin, and his LS placement looks too far back, then his pelvic angle looks steep (some of this is because he is resting his leg in every shot... But I think he just is steep too) with him standing as he is, I can't tell for sure what his hind leg set is like. He has nice bone.
Overall he's not the smoothest looking horse, I sincerely doubt he's destined for a Grand Prix career, but, he is probably a tough, hardy horse who may prove quite handy as his training goes along.
We used a number of these crosses (most looked a lot like him, conformation wise, too) when I worked with outfitters... They often made reliable mounts for mountain riding, could truck along all day, be used as pack animals, skid logs and pull wagon - generally just "useful" to have around.
