Prompt:

High definition photography. 32k UHD, highly detailed. Hyper realistic detailed photo. very realistic. photo realistic. 
Beautiful abstract bridge in an ancient alien city. wonderful magic light. 

Negative prompt:

blurry. Blur. unsharp. objects in the sky. planets. moons. 

Model:

Real Vision XL V50

Notes:

The model has difficulties with the "ancient alien city" and the bridge (or bridges) are mostly in a sort of rocky nature. The pictures generated are very fantasy rich. Guidance could be quite a few steps above 10.

You could try variations on where the bridge is, in a fantasy alien city, the city will appear. A jungle alien city  does hardly give a city. But the image is nicely green. Because of the word alien, planets and such tend to be on the sky. That looks less "realistic", so there are keywords in the negative prompt to suppress these.

The model Real Vision XL V50  is aimed at photo-realism, and that shows. This model can come with surprising results.
