Bless your heart. Just noticed that you started four threads here and four threads on another tattoo board. I have a job where I'm in front of computer all day. You see, we all have different kinds of jobs. NEAT!
I'm not sure I'd want to mix in Celtic with Japanese. It just doesn't make a ton of sense.
Graeme is right though. Best to go to an artist who does solid Japanese work and have them design something for you, perhaps based on what you are showing us here, but more appropriate for the style.
