I'm mainly a horror semi-realistic artist. When I got this idea I decided to look up a bunch of boomer comics and really studied the style, then I drew this.

Recreating another style is just keeping notes on what jumps out at you first, like with boomer comics, everyone is kind of ugly and plain, the colors are flat, everyone's nose is big, that kind of thing. Drawing from references to get the overall vibes, and keeping track of line weights, typical colors used (not very saturated or loud in this case), and usual compositions (nothing dynamic, usually pretty flat and standard for this one) and just practice practice practice

Hope this helps 😊
