Create a highly realistic, photo-style cover for an online course module titled 'Follow Up with Clients.' The image should depict a modern office setting where follow-up activities are happening. Focus on a professional workspace with a laptop open, showing an email or messaging interface, along with a smartphone next to it receiving notifications. Include visual elements such as sticky notes, a calendar, or a to-do list to symbolize organization and the importance of tracking interactions. The scene should evoke professionalism, persistence, and care, using soft natural lighting. Use a sleek, clean desk setup with neutral tones and accents of blue and gold to maintain a professional atmosphere. No text should be included. --ar 16:9  --s 750
