Prompt: An intricately detailed digital painting of a futuristic bullet train zooming down the tracks. The train is shaped like a giant stopwatch with clear glass sides exposing the complex internal machinery. The tracks are made of ripped price tag stickers floating whimsically in space. In the train's wake follows a colorful burst of stopwatch hands swirling dynamically. Vibrant skyscrapers and cityscapes are visible through the train windows. Cinematic perspective and angle captures a sense of speed and high technology. I included details about the train looking like a stopwatch, the imaginative price tag tracks, the swirling stopwatch hand trails, and the sci-fi city background seen through the windows. Let me know if you would like any changes or additions! I'm happy to refine the prompt further.
