I think that too much of her face is visible for a "Faceless Portrait "challenge. Perhaps a slightly different perspective might have worked better for you.
She quite definitely has a face, and a lovely one at that. The composition is quite nice with the window and the red reeds. However, for this particular challenge, I think less face would have served you better.
I really like to see people stick to the spirit of the challenge, so for me, there is just too much of her face in the shot to make this a really successful "faceless" entry. That being said, if she was intended to be the subject, I find that my eyes are drawn to the white of the vase first, the red stalks second, the white papers third, and her face last.
