Well she won't go grand prix, but for low to mid level stuff she should be fine.
She is level, which is good [or MAYBE slightly downhill, but I'm more tempted to say level], and her front legs are reasonable. Her neck set is a tad low for jumping, but acceptable, and considering she's an appy [right? She looks like one, and it's more than just the colour] not unexpected. I absolutely LOVE her hip size and angle, her shoulder is a teeny bit upright in the one pic but sloped in the other [slightly upright is actually a good thing in a jumping horse]. I really like her lovely short cannons too. And, AWESOME colour!
Now for the bad.
She has quite a long back. Her shoulder is a little bit closed, her hind legs are quite posty [this will limit her scope]. Her front pasterns might be a tiny bit too sloped. Her LS joint looks like it's a teeny bit far back and her loin might be a bit long and possibly weak.
Overall she looks like a good sound using horse, but will need to be conditioned carefully to make sure those front pasterns don't cause issues [then again my gelding's pasterns are very upright, so it might just be a matter of what I'm used to]. I don't see any reason you couldn't jump her.
A CLEAN SLATE FOR THE FUTURE
