Illustrate a highly realistic and intricately detailed scene featuring an elderly man sitting at a desk in an office setting. He is positioned behind a laptop, actively explaining the operations and functions of the company to two young women. Create a realistic and immersive office environment, complete with detailed furniture, office supplies, and appropriate decor. Pay special attention to capturing the expressions and body language of the characters to convey a sense of engagement and learning. Utilize cinematic lighting techniques to enhance the atmosphere of the scene, with careful attention to lighting and shadows. The final artwork should be rendered in UHD, 8K resolution, ensuring the intricate details and lifelike quality of the office setting
