I’m very very happy this worked out-- as someone who looked heavily into Friesian crosses (particularly Georgian Grandes aka saddlebredXFriesian/or draft). Too often Friesians and their crosses get a bad rep. I personally love the crosses that have been further developed with a purpose, such as the above, though many times the equine community makes me “second guess” friesian crosses I suppose. Still love them. I hope your friend won’t be given a hard time due to her horses cross typing, but it sounds like your friend is confident!
As for the mare, I agree she can gain a bit more weight. Her longer back is a bit typical of modern grandes (if she is one). She looks good to me from the picture.
