Nix began painting when he was 6 years old and took art classes in high school while also taking every opportunity to get out of class to paint stage sets or murals. He worked as an artist for the Knight Sign Company and has submitted paintings to the annual contest sponsored by the Alabama Department of Conservation and Natural Resources and Alabama Wildlife and Freshwater Fisheries Division since 1984.
After two decades of only coming close to winning, Nix's painting of a blue-winged teal was selected for the 2007 stamp. Following the win, he was ineligible for three years, but won the next contest he entered, for the 2011 stamp, with a painting featuring an American wigeon.
