This is a bit of an idiosyncratic list. Two of my favorite additions from my own youth: Hard Boiled by Frank Miller and Geof Darrow and Batman: Digital Justice. The latter now reads like a bit of a corny cash grab for the early '90s cyber fad, but I still love the time capsule of some if its art.

Also Frank Miller's Ronin has some amazing detailed full page artwork panels.

It took me twice as long to read Hard Boiled as it should since I spent so much time looking at Geof Darrow’s intricately detailed art. Great story, but the illustrations are on another level.

Batman Beyond is also technically cyberpunk although it has more of a Y2K vibe rather than the retro 80s / early 90s aesthetic.

It's not that idiosyncratic a list, those were the first two graphic novels that came to my mind when opening up the website. Geoff Darrow's art Hardboiled is incredible. I was a huge batman fan as a young teen and digital justice came out at peak Batman hype, and it was much hyped itself, but it wasn't very good.
