What I see that is good is she looks like she has the right length in her back to be able to really get under herself like you would want for spins and sliding stops.
Her head does not look quite as refined as what I think the more successful reiners have. Normally the head doesn't matter so much, its mostly cosmetic, but for reining you need a horse with a fine throat latch and refined head to really have the responsiveness the sport requires.
This may or may not be problem because she might be sensitive enough anyway. I also thought her neck looked a little short but I think it is the way she is standing in the photos like she is looking at the camera.
Depending on the level you are trying to achieve I think over all she is nice. Attitude, brains and heart can be enough too. So if she had the right "spark" and the willingness I think you guys could be a nice team!
