on your arm between your wrist and elbow is perfect IMO,the characters could be a good size there to look great,
be sure and find the right artist that does that kind of work,
and you don't want to read it yourself,it would be upside down,you want it so if you drop your arm and show it the person looking at it can read it.
and lastly but most important,be sure of the character's meanings 1000%
