As I understand it (and I'm NOT an arabian expert), arabs are supposed
to be shorter in the back and longer in the neck. Your little mare,
looked rather long through the back to me with a weak neck, almost
ewe-necked, although it could have been the angle of the video. She
also looked a little heavy in the head for an arab although that could
be just in comparison to the slightly weak neck, She looked a little back at the knee to me in one picture.
I think she is a sweet little mare but she doesn't jump out at me as being an ideal brood mare based solely on her confirmation. However, if she has a super temprament or is particularly tallented in a discipline that would definitely sway me in her favour.

They've put a man on the moon, but they still can't design a package for likits that you can open in less than 1/2hour
