I've got many aesthetics what I like and in which I want to create something one day, almost all of them are from XX century, because I just not interested in setting where automobiles and modern-type weapons aren't available (because it's two my most favorite things to draw, yes).
But two my most favorites are neon-style/retrowave/80s stuff.
And second is late 60s-70s-early 80s USSR.
I even thinking sometimes with merging that two styles and create something stylish, I've got some ideas and for that, but I certainly not having enough skill to do that yet.
But old action movie from 80s or a social realism is fine too anyway, of course.
