Just got done with this iteration of the bg. Next it to finish the cage light and lay some wiring across the top part. And yes, there is going to be a character at some point. It's Earth-chan from Concrete Revolutio, and she's likely going to be posed leaning with her back against the breaker box. I'll try to make it look cool, and it'll give a good sense of scale for the tunnel, which isn't actually that large. Thanks again for taking the time to keep up with this project.
