She looks good! She needs to work on getting her heels down and keeping her leg underneath her.
I do have to ask why you have spurs on her and a kimberwick on the horse. A kimberwick can be a harsh bit in the wrong hands, and she is just learning and you can tell her balance isn't really there, do you really think she's ready to handle a kimberwick without being harsh on the horses mouth? And the spurs..... she can't keep her heel down, much less use the spur effectively. Since she is learning, you should try to teach her how to properly use her leg, instead of giving her aids, or she will never learn how to have an effective leg. So try taking the spurs away and allowing her to build up her leg.
I also wouldn't be allowing her to jump until she can get her heels down. If the horse stops and her heels are up like that, she is going to go flying over the horses head.
Other than her heels over fences though she is looking really good! I would just be hesitant to jump her, since her leg position is dangerous.
She is cute, and you are doing a great job with her. I would just rethink some of the things that you are doing, and the pace that she's at.
Oh, and congrats at the show! you must be very proud!
