Please take my critique with a pinch of salt, as I don't do gaited horse conformation!
What I see is:
A looonnnnnggg back. It was the first thing I saw. She might be perfectly fine with that, but usually it inhibits them a bit.
She also looks pretty sickle hocked.
It might just be her stance (I really think it is) but the picture of her hind end makes her look very base wide.
I also see long gaskins.
I do however, like her neck, and how it types into her wither, and she has good front legs. Her shoulder isn't the best, but I wouldn't be too concerned. I like her head, and she has a sweet face. :)
