My first tattoo was a memorial tattoo for my uncle. It was a Raven because that was his favorite bird and company symbol. I had the idea in my head but I toyed with the idea of getting a tattoo until I was certain then went and got it designed but even then I still had a month to mull it over and made sure I was ready.
I love what I got and it is still the best tattoo out of the 4 I have so like everyone said think it over more till you are sure because it sounds like your really not ready.
