In his prolific career is a culmination of textbook artistic knowledge and keen aesthetic sense that has gone from a "slow and studied" application to "fast and free of precise thought". Craig's collections run the gamut from abstract expressionism to haunting, graphic realism, each one a reflection of its creator's unique vision. He is most well-known for his Populus series, which drew inspiration from a balcony overlooking Orange Beach, Alabama where patrons enjoying a wedding party seemed to form the shape of an eye where they stood. Craig explains, "Inspiration begins with a 'What if...' as I consider alternate imagery, surfaces, effects, results, etc. It comes from the past in conjunction with now. Like a bolt of lightning." Since the epiphany, his Populus series is now home to dozens of celebrities and icons of all ages including: Marilyn Monroe, Elvis Presley, Frank Sinatra, Freddie Mercury, James Bond, Salvador Dali, Pablo Picasso, Van Gough, Gandhi, James Dean, Lady Justice, John Lennon, Queen Elizabeth, Darth Vader, Michael Jackson, Audrey Hepburn, and many more.
