>>6045073I built a really neat Cloud City interior MOC when I was 15. I was experimenting with LED bricks at the time, and I came up with a long hallway with windows along it with orange and blue lights shining through to simulate what the actual weather was like. It looked good, it definitely wasn't anything extremely creative in terms of building, but it is still probably the best thing I've ever built.
My regret comes in from me scrapping it for parts. I used to have so much fun flickering with the lights in it and having Tantive IV like clunky shootouts with my Stormtroopers and rebel mini-figs. In fact, I still sometimes play with my Lego even though I'm 19.
