Various techniques such as pencil, acrylic paint, collage, photography, paintbrush and computer are combined in his illustrations. He always begins his work with a hand drawn sketch on paper, even when digital instruments are then to be used. Among the artistic influences amalgamated in his own unique and original work are expressionist painting, pop art, comics and posters.
