I love this one! Very nice work on it! It's like not just a space colony but also has a "resort" feel to it as well that I really like, it's like some place people would live comfortably one during their interstellar trip.
Maybe for future ones, like a "giant bug colony" like termite mound-themed, full of hives, coccoons, eggs, webbing or slime and such, or maybe the inside of a theme park funhouse castle?
