“This quirky collection of photos proves that a little imagination is the key to a good a picture. By simply using a collection of keys and a strip of chalk, photographer, Stanislav Aristov, 32, is able to re-create everyday scenes and objects. Stanislav wanted to show that even the simplest of items can help change your view on the world. After acquiring a large selection of keys from friends and family as well as local charity shops, Stanislav then went about scrawling anything from a key shaped rain drops to a key-eyed crab”. – Caters News.

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.
