this is very bad
its just blurry foreground obstructions with a blurry subject
please look at this picture carefully and practice applying it to photos
also practice keeping your ISO lower and avoiding diffraction limited apertures as much as possible
and stop using darktable if you are not a color science savant with weeks to kill on nonproductive software wank. even rawtherapee is better. better yet pirate a real program.
