Create a photo-realistic image of the men's freestyle swimming finals at the Olympics. The scene captures the excitement as swimmers from various countries stand on their starting blocks, poised to dive into the pool. Focus on the swimmer in lane 4, who is a cute koala wearing a colorful inflatable swim ring around its waist, with a snorkel and oxygen tank strapped to its back. The koala stands out among the human athletes, adding a whimsical and charming element to the scene. The background should include the vibrant Olympic atmosphere, with spectators in the stands, bright banners, and the shimmering pool water. Capture the dynamic energy of the event, emphasizing the anticipation and focus of the swimmers, while highlighting the koala's unique and adorable appearance, ready to compete in its own playful way, without including any text. --ar 1:1 --niji 6
