A winter beach with soft waves rolling onto the shore under a cloudy gray sky. Several identical figures, all wearing long coats and scarves, are scattered along the beach, walking in different directions but with a synchronized rhythm. They appear as if they are afterimages of the same person, creating a surreal and layered effect of repetition and motion. The atmosphere is cold and reflective, with the tranquil winter sea as the background. --sref <https://s.mj.run/SR8aRolDfDI>
