A heavily modded Red Rocket (the one from the main menu) and a few of the entrance to Vault 111, with holiday decorations. Completely put together in-game (this was my first time trying the settlement feature). Using the awesome Original Red Rocket by Ozzymander mod as a basis, i adjusted/resized/placed almost every object as well as multiple light sources (iirc i used around 20-30). Huge thanks to all those talented modders out there that made this possible and of course, Bethesda!
