American artist Javi Antunez tattooed the portrait of James Hetfield (frontman of Metallica) in a dark sided matter perfectly capturing perfectly the heavy-metal singer while performing the death growl. Hours were spent rounding up the artist’s facial expression.
Due to the extensive details, a tattoo will take about three to four hours to be done, like the raven, Franky, third-eye skull, or the girl with the face ripped off.
