Seven Tattoo Studio is an amazing shop with world class artists. Kevin Furness is an absolute animal. He took what I wanted and made it exponentially more awesome than what I had in my head. He is fun to talk to and pretty gentle with the needle.
If you look at his portfolio (Instagram: @kevinfurnesstattoo) he is a master of color and has a crazy range but he did a black and grey realism piece for me to a level that would make you think that's his primary method. I'd recommend him for anything you want to get done.
