Create a photorealistic image of a chubby white cat performing an extremely acrobatic routine on the horizontal bar during the Olympic gymnastics finals. The cat should be in mid-air, with its body twisted and spinning at high speed, demonstrating incredible agility. The background should feature a vibrant crowd, cheering loudly, with flashes of cameras capturing the dramatic moment. The lighting should emphasize the cat's fur and the dynamic motion of its performance, highlighting the contrast between its adorable, chubby appearance and its remarkable acrobatic prowess. --ar 1:1 --niji 6
