Always Watchful, American Indian puzzle

The image in this puzzle comes from a James Ayers original painting, Always Watchful (2005, Crow tribe). From the James Ayers website: Always Watchful is one of those compositions that reminds me why I became a portrait artist in the first place. Portraiture allows an artist to show expression and depict a thoughtful moment. I believe that, for the viewer, seeing someone in mid-action or mid-thought evokes a visceral reaction to the experience. More information about this painting and the artist, James Ayers, available on the artist's website: http://jamesayers.com/prints-and-giclees/fine-art-giclees/always-watchful-giclee/
