His name is Joao Carvalho and he's only 16 years old. But as talent has nothing to do with age, this artist already shows impressive mastery of the discipline he practices. 

He specializes in 3D drawings. To create them, Joao Carvalho uses a surprising technique that consists of drawing a grid pattern where he distorts the lines to enhance the illusion of depth.
