I did this about a year ago or so. I dig retro-wave concept from 80s movies or music, so I just made something up. It's about a former-gangster guy who's had a double-barrel shotgun and a Mustang, hunting for someone in Chinatown who did bad things to his girlfriend. I never had a chance to continue this artwork into some kind of webtoon comic or whatever, even if I wanted to.
Maybe some time.
Enjoy.
