The creation of Domino was inspired by two things:
The concept of what becomes of pretty cat boys when they're past their youthful prime? And the entirety of the song "Domino" by the Cramps.
I really really dig that song.
Sometimes it's fun to just design a character, get a base concept to play around with, and then wing it from there with the detail development. It is truly one of my top favorite hobbies! To just make a design that speaks to me and then "yes and-" them into something fleshed out and multi-dimensional!
