hummm... tattoos are very personal, each one you get says something about yourself, who you are, and what you love and believe in. I think that you should think this over long and hard. I think that you should come up with your own idea, then talk to your artist and see what suggestions they have to enhance things.
I know your looking for some ideas, but it will hit you.. one night when your sleeping or whatever, who knows, but when it hits you, you will love it!
and also.. just curious... are you wanting fw or sw??
