I suspect you'll have much better luck directly implementing the style you want rather than trying to get a (current gen) AI to reliably generate ANSI art. This video is a nice overview of implementing a variation of the style in a post-processing shader: [VIDEO]

Definitely something I want to do down the line... something like the Sobel filter approach that acerola uses in this video: [VIDEO]

Cool, might want to consider going even further, and add a full ascii player to it :) [VIDEO] (Acerolla did some crazy stuff but as a filter, but others have done it in actually consoles) [LINK]

> I don’t believe I’ve ever seen shape utilized in generated ASCII art, and I think that’s because it’s not really obvious how to consider shape when building an ASCII renderer. Acerola worked a bit on this in 2024[1], using edge detection to layer correctly oriented |/-\ over the usual brightness-only pass. I think either technique has cases where one looks better than the other. [1] [VIDEO]
