I ride Arabians in jumping and everyone that doesn't know me thinks I'm crazy, but hey if your horse likes it then go for it
it's all in the conformation
Any horse can make a good jumper if they enjoy it!
That horse could be a fantastic jumper! As long as it is conditioned properly it could be an extremely athletic powerhouse.
It can be a very good jumper. Just because Andalusians are not often seen jumping doesn't mean they're bad at it... Last time I saw one, it jumped a meter and thirty...
