 It features a person riding on the back of a large fish that appears to be flying or floating in the air. The person is dressed in what looks like medieval or fantasy-style clothing, including a tunic and a cloak. They are holding a long staff or pole with a hook at the end, which is dangling down towards the ground.

The fish itself is quite detailed, with visible scales and fins. Its body is elongated, and it has a somewhat serious expression on its face. The fish seems to be gliding effortlessly through the air, as if it were swimming in water.

Below the fish and the rider, there's a landscape that includes a town or village with several buildings and spires. The buildings have a European architectural style, with pointed roofs and towers. The landscape also features rocky terrain and some trees scattered around.

The sky in the background is overcast, with thick clouds covering most of it. The overall color palette of the image is muted, with shades of green and gray dominating the scene. This gives the image a dreamlike and otherworldly quality.

There's also a signature or watermark in the bottom right corner of the image that reads "TOMOYO," which might be the name of the artist who created this artwork.
