20 anniversary Karate shirt

This is what a business in United States was looking for in their t-shirt design

I am in need of a "cool" design for our 20th anniversary shirt. My logo (attahed) has purple, gold and black in it but I don't really have an idea for a shirt. Only that it should appeal to 8-16 year olds but would like to be worn by adults as well. Maybe an "affliction" style full artwork would be nice. Maybe something that is not centered but goes from back to front or examples of each style would help. Ying Yangs as well as Snakes, dragons, tigers are all associated with Karate but I'm not sure how that would look. I also don't know if the design should have multiple colors or limited. Different ideas would help. The dates are 1993-2013. I'm not sure if that should even be on it or just something say 20 years and still kicking (or something represent being in business for 20 years)? Read more
