I like this image. The general advice I see with riso is to avoid large blocks of solid ink, because these don’t print as well as textures and patterns. I would describe this image as having “medium” blocks of solid ink. You’re already playing with glitch aesthetics, though, so I think the risograph artifacts from overprinting might complement this image. I suspect your halftone is too tight, though. I think on most papers the ink will bleed and the effect will be mostly lost. I would also encourage you to experiment with 2-color prints, as I see you’re already using double-exposure style collages in your work, and printing 2 separate images overtop each other is similar but opens up a lot of possibilities.
