Animate a scene where multiple men are walking. The animation should capture the natural movement of their legs and arms, with a slight sway of the torso. The walking pace should be synchronized, but each character can have small variations to make it more realistic. The background should have a slight blur to emphasize motion. The lighting should change smoothly to create a dynamic effect, as if they are passing through different light sources. The overall feel should be fluid and natural, making the characters appear as if they are genuinely moving through a real space.
