that looks like a better option..I figured the art department could clean it up and make it simple. But here's a simpler design.
the lettering, kanji outline and the dragon would be metal.
The die is made and those are the raised surfaces of the pin. Everything else is filled in with a glass compound. (could do this with soft enamels but they seem cheap and the color can come off later)
This looks like it would rock with the black nickel plate
