His drawings concentrate on documentation and communication, as he illustrates from memory the ever-changing space of street life and culture. On paper Greenfield impresses the silhouette and patterns of contemporary dressing, subsequently creating intimate social portraits of places and their communities. This drawing process honed on Australian streets has since taken Greenfield across Japan and even to France to report from Paris Fashion Week. Now a freelance artist and illustrator, Greenfield uses blogs and social media to share his drawings and collaborative projects. Greenfield has exhibited in Australia, as well as Japan and is currently based in Melbourne, Australia.
