You have a lovely horse! I think she is very representative of the breed. I may be way off base, but she does look like a foundation QH to me. She is very balanced, eye appealing. The only "pick" I have is her neck, I always like a loooong neck, but that's just me. If you let her bridle path grow out and keep it at about 2", maybe 3", it will also make her neck look longer!
I see my thighs have grown since the last time I wore these breeches........
