realistic man 3d model

Create a highly realistic 3D model of a middle-aged man walking with a natural, relaxed stride. He is wearing a white shirt, black pants, and black sneakers. His posture and body orientation should suggest he is walking alongside a child (the child is not included in the model). His head is slightly turned to the side, looking down with a warm, happy expression, as if checking that the child is okay. Focus only on the man. Include realistic skin shading, natural proportions, and detailed clothing with fabric folds. The pose should feel dynamic and believable, suitable for high-quality rendering or animation.
