Using the second image (with the two rings) as the main subject, replace its background with a plain, smooth, even white surface, similar to the clean style of the first image. Remove the candles and flowers completely. Keep all the other Cartier items: the two rings in their open case, the larger red box, and the red shopping bag. The text on the left side of the image must be preserved exactly as it is. Make the overall lighting of the scene much brighter and cleaner.
