Beautiful photo! It has a very Native American feel/look to me (even though she is adorned like a hippie child) and that she could be praying to her spirit guide. --> The 3rd of rule alway's ticks me off in that people are so strictly and stringently adhered to it . Sticking to rule's can limit your creativeness sometimes!
I like it, great lighting, color and atmosphere. The only thing I would maybe change is not having her in the center of the picture, could move her to the right of the frame. I think this would give a visual flow from top left to lower right.
