Enhance Image for Wall Print

I have a high-quality image of Virat Kohli, MS Dhoni, and Rohit Sharma together in one frame, which I want to further optimize for printing as wallpaper on a small wall (up to 8x10 feet). The goal is to ensure the image maintains its sharpness and clarity, even when zoomed in or enlarged. Specifically, I want to increase the resolution for sharpness, improve the colors and brightness, and remove any noise or artifacts. The end result should be a vibrant, sharp image ready for large-scale printing without any quality loss.
