I ran across these pics of these black and grey skull tattoos from a while back. We started with the skull and piston tattoo on his arm, and a few months later he came back to add onto his chest and complete his half sleeve tattoo. We did the skull with spark plug tattoo on his chest, and we added gears to his skull and piston tattoo on his arm. We tied the whole piece together with black and grey smoke to pull it together as one complete half sleeve and chest tattoo.
