Create a glass terrarium scene showcasing a vintage scotty bike, positioned prominently on a lush green grass base. The bike should be a classic model with chrome accents and a pastel color, embodying a nostalgic charm. The scene should be illuminated by soft, natural light streaming in from a nearby window, casting gentle shadows inside the terrarium. In the background, include miniature wildflowers and pebbles to enhance the natural feel, while the foreground should feature a small, decorative fence surrounding the bike, emphasizing its vintage aesthetic. Use a shallow depth of field to keep the focus sharp on the bike while slightly blurring the background elements.
