When Ola started out as a graffiti artist, he would often fill the letters with skulls. Soon this became his trademark. Later he evolved into creating more abstract murals with liquid shapes. For the POW!WOW! Rotterdam 2021 festival, he initially wanted to paint in this style, but he had difficulty fitting this in with the neighboring pieces. He then decided to go back to his signature skulls.

This piece flows into the artworks of Engin Dogan (left) and Andre HZS (Right), which were created at the same time.
