I once saw the original concept on 穂積桂月's twitter, thought it looked fun and decided to make it. I admit it lost some elegance in the transition, but it's the first time I'm doing something not based on a blueprint. Wish I could work on this some more(wanted to make a more detailed interior, and a moving observation elevator, and a good tropical environment, and better window textures, and...), but I'm out of time for now. So here's a bare minimum. Maybe I'll come back to this later.
