Kling 2.5 Turbo (pro)
Create a 30-second portrait video illustrating a philosophical metaphor of a person like a train pulling dark, mysterious, inherited carriages, representing hopes, fears, and past. The video must be seamlessly loopable, so that the ending visually matches and smoothly transitions back to the beginning. Ensure the train's motion, lighting, and background allow endless repetition without any abrupt changes or jumps. Atmosphere calm, meditative, and realistic.
