Well, for that matter most of people shouldn't have their tattoos, because most of peopel I ask about their tattoos they don't even know what they mean, they simply like how they look.
I want to represent certain values or things with runes; This runes happen to belong to a culture I like too and a culture I always wanted to get close to ever since I was a child and I am slowly getting there. So it is definitely a good idea for me to do so.
Therefore not only it makes full sense for me, but I also happen to like how it looks.
As you said, I need to find some "expert". and that's why I am doing my research. I don't expect to find it here, but if you don't look for something you definitely won't find it
