The concept sounds really distinctive, especially the contrast between the darker post-apocalyptic setting and the stranger details like Nacho and the recurring EVAC 87 mystery. I also like that you’ve already built the full game before looking for the artist, since that gives the visual direction a much clearer foundation.
For a project with an anime/hyper-real style, I’d imagine keeping the character designs and environments visually consistent across all ten zones would be one of the bigger challenges. Do you already have a defined visual reference or a few key scenes that show the exact style you want the artist to follow?
