Backpiece on a Mr. Driscoll from Florida. Yes, he goes scuba diving. He contributed heavily to the design and style of his skin art. Placement of this tattoo is somewhat indicative of someone who usually keeps themselves totally hidden, as confirmed by him when I asked. The coverage however is incredibly dense and quite beautiful. The detailing is quite precise, rendered in a very photorealistic style, and this photo really does not do the art justice.
Styling is a bit unique in that the upper back and arms are left blank. On most extensively tattooed persons, the arms and upper back are a starting point.
