I really like these little buildings I picked up at the Arcade Gacha. Although they are obviously meant to be futuristic, they have softened over time. The colors and details are cute, not entirely grunge, and a few persistent trees to keep them from looking too dystopian. That's encouragingly optimistic! I dressed them up sparingly with a bench, a lovely classic car, and a few lights.
