For a non-Native woman to wear a headdress, or even a model headdress, is extremely racist and disrespectful. This is a sacred object to these people, not a fashion statement. It's a shame, too, because you seem talented. There are so many other things to photograph--perhaps actual Native people wearing regalia as it should be worn?
I really like the angle and the scope of the shot, as well as the color, but I take issue with the theme. I feel that the title of the photo and the model's headdress and pose are disrespectful to the dignity of Native people for the sake of an "exotic" photo shoot. I applaud your technique, but not the subject matter.
