I think it depends what level and discipline of jumping you're looking for. Her build wouldn't suggest she'll be a top Hunter or a GP jumper, but I don't see anything about her build that would stop you and her from being happy over smaller courses. She doesn't have a typical hunter "look", but her form over fences and movement would be the most important factor in telling if she could be successful in the hunter ring at any level. Her scope, natural proclivity towards being careful and handiness would be the important factors in determining her success in the jumper ring.
The things I like her about her build for a sport horse are that she looks reasonably level in these photos - she's not built too downhill. Her pasterns have a sufficient slope to them and, although are on the shorter side, do not appear to be excessively short. In the second picture more than the first, she appears to be a little over at the knee, but her legs appear clean nonetheless. The less-than-deal things for a jumping horse are that her shoulder angle is a little bit more closed and the point of shoulder is a little lower than I'd like to see on a sport horse. Her neck is set a little low, and I prefer a sport horse to have a less sharply sloped pelvis and a lower set stifle.
To really assess a horse's talent for any jumping discipline, one would need to see how the horse moves and how the horse deals with jumps - even small ones. Conformation can tell you about likely attributes and skills, but a still picture can never give all the information you need to assess a horse's abilities. Good luck with your horse!
