Wartena's work is narrative, based on himself and his surroundings. Executed in the form of drawings, comics and installations, it features friends, family and scenes from his daily life.
Wartena likes also to think of his work as snap shot photos, similar to the photo albums his mother has of him since he was born: a personal history book of his life. For Wartena, creating work is a way of preserving his ever-changing reality. He sees beauty in the ever-day world. With his work he wants to make the viewer look at their surroundings with new eyes and see what he sees, beauty in the mundane.
