What is the best place for a tattoo?

I have 5 tattoos 3 of them are big!! Lol I'm 21 female. I have one on my wrist that I love...the back of ur leg would be nice like above the ankle/below the calf ( if u understand were I'm talking about lol) or the back of ur neck would be cute if ur hair is pulled up. Just I'd suggest not putting a small tattoo on a big space it looks off to me.
