I know nothing about HUS so will critique from a jumping standpoint.
Bear in mind low-level jumping is within reach for nearly any horse!!
He is quite downhill, which will make getting his front end up more difficult for him. This may mean he has a sloppy front over fences, which grid work and gymnastic exercises will tidy up to some degree.
I like his nice short cannons, they will stand up to some decent work. His shoulder is quite nice too. He's a bit posty in the hind, which will limit his scope some, but not as much as the downhill factor. I'm not sure about how his neck ties in, it's not too bad into his chest but there's something I don't like about how it ties in to his wither.
I love his head (I know, totally irrelevant for jumping ability). Pasterns are a bit short and upright, and he's a bit light on bone.
All in all for lower-level jumping he should do ok but will not be a higher-level jumper.
YES I KNOW he is only 3 so he might level out some and the downhill factor may not be so bad when he's properly matured. Then again he might not. He is a stock breed and the majority of the population of stock breeds is downhill - it's what they're bred for, downhill is GREAT for western disciplines.
