So here's mine. It's a little more cartoony than the others. As you can see, I took the Hano symbol and flipped it on its side after modifying it a bit to be the "Z" in his name. I would have liked to put it under the line of his neck but you said you wanted it underneath so I did that. I can change some things if you are seriously considering mine. If you do end up using my art, please send me a little something in return as I do normally get paid for my work, but it's mostly for my pride, ha. Enjoy!
