On a cool rainy, overcast day in September, Staff Sgt. Nakoa Akin Moonblood — formerly Staff Sgt. Roby Luckett — finds himself immersed in a vibrant bounty of artwork in the Circle of Art tent at the Indian Summer Festival at the Henry Maier Festival Park on the Milwaukee lakefront. As one of the featured Native American artists, he has more than a dozen paintings on exhibition. While this might make some people nervous, Moonblood is not. He has a quiet confidence that perfectly matches his stoic exterior. He sold every single one of his paintings, which most definitely gives him something to be confident about.
