This is one of the sets I art directed for Eternal City Season 1, for Storyscape. Super proud of how this image turned out. The fiction is that It's a repurposed mysterious facility built by an unknown race, that the humans took over and turned it into a prison. The humans used what ever they can find to build prison bars, walkways, etc. And over the years, colorful mushroom and fungus has grown everywhere, giving the dark space some warmth and color.
