The client asked for a sort of biomechanical which included his passion for Harley Davidson bikes. He liked a lot my work on “Mechanix Strings” and wanted something whit the same feeling. The link between skull, Hells Angels and Harley was immediate, so I thought to add some stylized wings and biker’s glasses. The idea to apply the tires design to the skull was very nice. Besides I included some mechanic elements from the Harley Davidson. It’s not really a biomechanical but I find the composition very satisfying.
