Can Anyone Help Me With A Tattoo Idea?

Hello, I know for a fact I will not be getting a tattoo sometime, because for one, i’m only sixteen, you must be 18 to even get a tattoo in wisconsin (with or without parental consent) and so, I am really thinking about this tattoo and I want it to be perfect and something meaning full. I have this idea of having three small butterflys with birthstone colors of my grandma (ruby- because she has raised me since I was small and is still going strong even though she is 83) my mother (light green – because she is my mother. ) and me ( golden (topaz) because i complete the circle of three generations). I really love this idea and I would get these three butterflies on my left shoulder blade. However, i really want to also include my father and my brother. I also want more behind the butterflies and i was thinking of maybe doing one butterfly with something from each person that makes me remember them, for exampe, my father was in the navy during the vietnam war and I’m very proud of that, so i want to deffinetly represent him with an anchor. But i’m not sure how I could do this, does anyone else have any ideas, I want it small and it doesn’t even have to include butterflies.
I know that I that just because someone on yahoo answers tells me an idea i will not go off and get that tattoo, im just using these ideas to help me come up with more ideas.
Thanks:D
