So I got a half sleeve done about two years ago on my upper arm, all different things referring to my religious beliefs, I got everything I asked for. Liked the work and there was an open spot left that is nearly the entire back of my arm. Since that I have had a little trouble getting ahold of the artist(not impossible) just kind of feel like I have to bug him to get a reply, and he made it very clear he wasn't too fond of doing Christian tattoos, if I decide to fill that spot would it be wrong of me to go to another artist to have the rest of my sleeve finished since it would be incorporated with his work? I know there is alot of unwritten rules in tattooing and I don't want to piss anyone off. Just would like to finish my sleeve and have it done by someone who isn't tattooing something they don't like. Please give me your opinion.
