Hey whats up gregxx12 In my oppinion the neck would be an area that would be quite sensitive as well many of my customers have set quite well during one on the neck, sides and back, however I've never done one on the front though., Nor have I done one on the forehead, again in my oppinion I would not recommend getting on the forehead.
For the right kind of person, a forehead tattoo can be great. I know an artist in my city who has a tattoo on his forehead--but he's extremely eccentric (even moreso than I!) and he's the only person I've ever met who could pull it off. Still, there are many people who think he's too weird for words. When I first met him I was a child and for six months before we met (he lived down the street) I used to cross the street rather than walk near him! lol
