First ever tattoo!

Mo
I'm planning on getting my first ever tattoo in a few weeks. I'm excited but also nervous - I don't even know what about, as I like to think I do quite well with pain, and I know the tattoo has meaning  for me, but there's just a bit of worry still. Any advice/tips/reassurances would be great!
These are some of the designs I'm looking at for a general idea/inspiration, and I think I'd like it longways on my wrist :)
