I've had Nigel Hirschi do two of my tattoos since I moved to Arizona. He's probably the most laid-back dude you'll meet, but super careful and professional. Both times I gave him the artistic freedom to choose the colors on my tattoos (I'm not creative, leave it to the creative people) and he drew them both up himself, not a tracer.
I can't believe how great he is with color and just making the little details perfect.
Something I also very much appreciate in an artist is that he doesn't talk to you the whole time while you're getting tattooed. I don't know about anyone else, but I like to lie there and zone out, and I really don't like to talk while getting tatted.
Both times I was VERY happy with the price (have you seen prices for Phoenix artists?!?!)
Of course I will be returning to Nigel to keep getting work done, and recommend him to anyone who asks.
