Sporting a feathered mohawk, Arizona Muse communes with a crow in James Houston’s short for his green initiative, Natural Beauty. A mix of still and filmed portraits, Houston’s project features foremost environmentally conscious celebrities and top models—including Emma Watson, Brooke Shields and Karlie Kloss—and simple natural objects. “I was looking at the relationship between man and nature. We are really one and the idea of including the crow and Arizona worked well to illustrate that,” explains Houston. “It’s a dramatic journey of flight.” The images are showing at both the New York and Los Angeles outposts of MILK gallery and are showcased in an accompanying book that released in conjunction with World Earth Week 2013. Houston has shot innumerable campaigns for the likes of L'Oréal Paris, Donna Karan and Gap, but Natural Beauty is a project close to his heart and aims to raise awareness and funds for the non-profit Green Global USA, with all book royalties and a hefty percentage of print sales going directly to the environmental cause.
