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

The artwork illustrates a submarine speeding in the sky with its large, spatial rear spoiler not configured for aerial dynamics. The vessel features two main downward fins on the top and a plethora of tightly closed port openings designed for bright daylight function. Its topmost bridge features no transparent windshield and the floating device is adorned with a big downwards number, illustrating perhaps its rank or designation in a series of sky-submersibles. The overall impression gives the artwork an aura of subaquatic voyage reversed into the clouds.
