( Not my Model )

https://civitai.com/models/2842086/316-vectordelia

This style is inspired by the "vectordelia" or "frutiger metro" aesthetic that was popular in the mid-2000s to early 2010s. I don't remember it being called either of those names back when it was popular, but it's what aesthetics wiki is calling it now so I'm going with that. This style is characterized by vector illustrations embellished with swirls, halftones, stripes, or splashes. Backgrounds are usually solid color, have rays, or other subtle vector textures.

This is a strong style so you should be able to see it with only the trigger "n0vuschr0ma style", but you can add "vector illustration" if it needs some help. You can customize the swirls by adding "vector swirls, halftones, splashes, splatters, leaves, flowers, hearts, stars"... or whatever is relevant to your image. If you want the rays, you can ask for "rays" or "radiating" for your background.

You can also ask for your subject to be "on" a background scene to create the look where the subject is separated from the background by the swirly embellishments, but it often does that by default anyway.

I trained the initial version with only royalty free stock I already owned from that era, then I edited those generations to create a more diverse dataset.
