We don't often have many people post with Irish Sport horses. I know, because I ride one! He's not mine, but I get to ride him from time to time.
Anyway, as for your girl, the first thing that stands out to me is that her front left leg seems a bit crooked. The knees are nice and big and the canon short, and in fact, her bone is amazing. But, there is a strange angling outward from the knee down, and the appearance of that hoof toeing inward.
I can't say much else about her hind end because none of the photos show her squarely from the side, with her legs squared up, too. She does have upright shoulder , same as the horse I ride. But she is much less "drafty" than 'my' ISH.
