Roberto creates hand sculpted bas-relief designs from the organic medium he developed. The medium dries hard and has the appearance of stone. Painting the finished work with acrylic, or bio "green seal" paints. Sometimes leaving it natural earth, plant or spiced colored, he seals it with acrylic clear coat. Enhancing his work with sand, glass, stones and metallic finishes makes a beautiful natural contrast on the sculpted surface. His medium is composed of non-endangered sustainable plant, wood, flowers, earth and stone. Elemental Art & Design using traditional Chinese Elements of Earth.
