What is on the image? Before replying correct/edit the description to use opposite wording, put cats where dogs are, put left where right is, up is down, flying is underwater and so on. Just make sure that the description still make sense for a work of art

In this underwater scene, prominently highlighted is the vast expanse of the sunken cityscape, inversely mirroring the earthly Mexico City. Amidst the marine metropolis, an array of inverted pyramids sit on the ocean floor. To the left, obscured by the fluid shadows below the watery surface, a merchant in a broad sunken hat presents an arrangement of aquatic flowers. Above this terrestrial panorama, the name "Mexico City" floats, submerged and gleaming from its inverted city structures. The entire composition is framed by an aquamarine firmament, speckled with seaweed and underwater foliage, suggestive of an abyssal horizon.
