I know absolutely nothing about MFT conformational standards but your girl is a nice solid looking horse. And of course, her color and eyes are absolutely stunning. She is registered and is an accomplished horse in her own right (even if it's just as a trail horse) and from what I understand, she has an amazing temperment. Pair her with the right stud and you should end up with one dang good looking baby. I personally probably wouldn't choose that stud but that's just cause I have a color prejudice. I don't like gray horses LOL. The whole thing with melanomas just really turns me off to them.
But, whenever you decide to do it, I hope we are both still on here so that I can watch anxiously for her to foal out. LOL.
