I like her neck and shoulder... I think she is both back at the knee and tied in behind the knee.
I don't mind her back length, but she appears to have a long loin, but her LS placement isn't bad. At this point in her life, I wouldn't expect either of those to change. She is downhill in balance right now, she might come level but it's no guarentee - She does appear to be lacking a bit of pelvic length, a bit steep in pelvic angle and may be post legged as well (with a young horse you take a gamble, sometimes by three those angles are much as they will be when done, sometimes they will change)
To me she looks light in bone as well.
Honestly, she has conformation that could be worked with,to some degree, but not ideal. If it were me, and I wanted a horse that could carry me onward in Dressage, I'd keep looking before I went back to her.
