Are you influenced by any particular artist/s? What medium do you prefer (and why)? Why do you paint by hand rather than using a computer graphics program? How much of your time is spent painting/drawing? How long does one design typically take from start to finish? Where do you get your ideas? Do you sell your work - if so, where? Do you enjoy the promotional side of selling your work? Do you have any advice for other would-be greeting card designers/illustrators? What are your plans/aspirations for the future in relation to your art? paper collage. The background is black and the name, Oliver, is written in coloured paper letters and sprinkled with red, yellow and orange stars.
