Wrong choice?

I have been waiting the majority of my life to get my first tattoo, they are something I have always loved and are amazed by them. I want something has a meaning behind it that I can relate to. Over the past few months I have been stuck on what I have seen about the Celtic Tree of Life. I found a design of it that I like, but altered to make it my own, but now when I look around ht doesn't seem authentic to the celtic culture. The most common version of this design is either too plain or too masculine for me. I am not a very fiminine girl, but I want something a little more...me. Does anyone know any other designs of the Celtic Tree of Life or have any advice pertaining to my problem?
