Hey there gablee,
Have you had a consult with a tattoo artist yet? That’s really where I got a lot of my answers and help. I met with my tattoo artist and went over all the possibilities and let him put some his ideas down to see how it all looked. He knew just the right lettering and size to go with my portrait tattoo. You might try that and looking through some portfolios to get some ideas. Good luck and I hope you come back with some pics when you have your tattoo!
