Hi
Easiest way is to google image tiger or Japanese tiger and download several of the images you like.
Then take the picture of the shirt and tigers to a reputable artist and get a custom job drawn up.
They can base it on what you want – I took my backpiece design and said I want a more realistic tiger adding facing the other way and it was not a problem.
Just takes a little longer as they need time to draw it up.
Not knocking flash but many of them are not brilliant pieces and if you are gonna go for a serious tattoo I always say go custom.
Take Care
