Create a highly realistic, photo-style cover for an online course module titled 'Follow Up with Clients.' The image should be divided into two sections. On the left side, show a professional loan officer at a sleek office desk, engaged in a phone call, with documents, a laptop, or notes nearby to reflect an active work environment. On the right side, depict the client in their own environment--either at home or at work--holding a phone and responding to the call, with subtle details like a coffee cup, desk, or comfortable setting. Use soft, natural lighting to create a welcoming and professional feel on both sides. The scene should evoke connection and communication. The color palette should include neutral tones with accents of blue, gold, and white to maintain trust and professionalism. No text should be included. --ar 16:9  --s 750
