Ernest Zacharevic is a street artist whose photo-based murals have been cropping up all over Europe, Malaysia, and Singapore. Most, if not all, of his work is site-specific. The first thing he does when making a new piece is to take lots of photographs of the place before choosing the angles with which to paint his subject. He said: “Working with children allows more anonymity, I don’t consider my artworks to be portraits of a specific person, rather a universal experience.” His subjects can be seen interacting with real objects like bikes, motorcycles, chairs, shopping carts, and even roofs.
