I cannot remember the first time I saw a yin-yang, but all I've known is that I've always associated it as a mask of sorts. Don't know why, I just do.
And considering I've never encountered anyone who personally sees a mask every time, when it came time to make a persona of sorts, it just seemed fitting.
It was also the first inspiration of mine to make an unofficial Pokemon design, so using that as my "mascot" was cool for me. I'll post about it later, but it's basically my version of the Gen.5 original dragon.
Have never understood why people still try to draw it as some amalgamation of details that just happen to look like the Tao Trio, that's some backwards logic.
So when I post the design, what I went with is well, a spirit of sorts. It's literally a wispy ghost wearing the Yin-Yang like a mask.
The hat is a fedora, and I just wanted to be original and/or cool when I drew it. I don't even wear a fedora anymore...
