I started regarding my Illustration as jigsaw puzzle, placing sets of colours and shapes in most appropriate places. I see it differently from drawing, though they both have the same root but when shapes, textures and composition get so much say in the picture, you must depart from the idea of doing everything in line. It's simply more complex.You have to bring in concept of co-ordination and arrangement of sets of visual components. Shop window displays show me a lot of clues. And the fonts are so essential now that it gives extra meanings and charms to the picture.
