I have a very specific taste in tattoos
I generally don't like them, mostly because it's just a picture stamped on human skin. Or some symbol stamped on to you. You know, you can put that stuff on a piece of paper as well.
However, I do like tattoos that involve the shape of a body, that goes around the curves in a smooth way.
Also make it look like a whole. I don't like it when a girl gets a small tattoo, then another somewhere else, and another and another and then it doesn't fit anymore and they have to connect it into something that looks original, but it's usually just a bad mix. Either go for a nice large elegant piece at once, or don't do it at all.
Sorry if I insult anyone with this
