Phillip Hua addresses environmental concerns through the use of everyday materials like newspapers, construction paper, light, and time. In the 'Re: Action' series, the artist works on the relationship between nature and commerce, and the aesthetic boundaries of painting, collage, and digital art are themes explored. He contemplates nature's role as commodity in contemporary life. Compositions of animals, flowers, and trees, reminiscent of Chinese brush painting, are painted on financial newspapers.
