He has strong rounded hindquarters, will be good for jumping...
Shoulder seems slightly upright so I would be curious to sit his trot, could be a little choppy.
Good angles on his fetlocks, canons are nice and short, feet look good.
Back seems average to long, so would want to watch his weight to make sure he doesn't have back problems, but he seems like a really sturdy horse so it may never be an issue.
I can't tell exactly where his withers are because of his fluffy mane, but in the first photo they almost look lower than his rump, which could make it difficult for him to collect, but perhaps not.
From the jumping photos he looks like an earnest, hard worker who has been taught well. Knees are high and together, and he is rounding nicely over the jumps. Will definitely get you some ribbons in hunter.
Hope that helps!
