Lokesh Padmashali starts with the eyes. His stylus moves swiftly over his Samsung Note, and soon the squiggles take shape. A face forms. All the while, his stylus has been dedicatedly stuck to the screen; he hasn't lifted it even once. In all, it's hardly taken him 30 seconds to make a portrait. "A single line has endless possibilities," says Padmashali, 31. A graphic designer employed at a design firm in Prabhadevi, Padmashali has mastered the technique of making a single line bend to his wishes. It is there for viewers to see. On his Instagram account, @lokeshpadmashali, the artist has a virtual sketchbook, where he has uploaded 145 such sketches.
