23-year-old Julia Koceva has taken the internet by storm with her impressive drawings created using an old technique known as stippling – creating pattern and applying varying degrees of solidity or shading to it by using small dots.

A criminologist by day, Koceva spends her nights working on her amazing drawings. She takes between 40 and 100 hours to finish a piece, painstakingly applying tiny black dots to a large piece of paper, using nothing but a ballpoint pen. As Alphonso Dunn, author of “Pen and Ink Drawing: A Simple Guide,” says, stippling creates a unique texture but requires patience and a meticulous approach. It’s a technique that requires nerves of steel and mountains of patience, but the end results are nothing short of awe-inspiring.

The young Swedish artist draws all kinds of things, from realistic animals and flowers to musical instruments, but her most impressive artworks are definitely the celebrity portraits. Her collection features portraits of pop icons like David Bowie and Jack Nicholson, with everything but their hair made up of thousands of tiny black dots.

Even though the thousands of hours dedicated to creating these beautiful works of art have taken a toll on her health – she has developed carpal tunnel syndrome – Julia Koceva continues to draw and captures the imagination of her fans with every new piece she posts on Instagram, where she has over 68,000 followers.
