I think it borders on the dialogue containing a very rigid formalization
Could you please elucidate what a "rigid formalization" means in this context? Demonstrate it by example?
So what do you want us to comment on?
The language of the excerpt. In particular, I'd like to understand if such adaptation looks natural for native English speakers.
the realisation our style has/needs to evolve, and rewriting to match that, is part of writing
My style is quite mature and evolved - in my native language. Maybe it can and should be further evolved, but one first need to at least read the source text to make such suggestions. And, sorry, I have no intention to change my style only to better adapt it to one of hundreds of languages existing in the world. I don't want to sound as a foreigner when writing in my native language. Besides, if tomorrow I got the idea to translate my novels into Chinese or Swahili, should I learn that language first and then rewrite my novels again?
My crit remains the same - it reads stilted, translated, and not smooth.
Could you please take a couple of sentences that look stilted and not smooth and rewrite them to look natural? Only one condition: any words related to Christian religion ("God", "holy", "hell", "devil" and so on) can't be used.
However, I also wonder how much may be lost in the translation.
Any translated text always loses and acquires something. I personally always prefer to read books in their source languages if I know it. However, I believe this text should keep most of its original quality.
From your comments about integrating the "unusual" elements into the world, it sounds like the contemporary fiction genre called magic realism.
Well, the concept of "genre" is different in different cultures. There is no place for real magic in my books, I always stay within the limits of hard SF, and events usually take place in different worlds, not on Earth. However, to me, science fiction is "fiction" first and only then "science". On my planet, my genre is defined as "social science fiction", i.e. it's all about people and society. Fictional elements, even if they play a major role in a story, are always secondary to characters and the society.
