These hyper realistic drawings are so lifelike they could pass for photographs. The incredibly detailed works of art were created by self-taught artist Ivan Hoo, from Singapore, who earns a living from his realistic drawings and paintings. The 31-year-old takes up to three days to complete the impressive pieces, which include animal portraits and still life drawings of everyday items such as a Starbucks cup. The A3 sketches are completed using a range of soft pastel pencils and are drawn from still life, or a photograph taken by Ivan himself. Here: Ivan Hoos drawing of a pug.
