I think your noise reduction looks great, @plantarum! And I can’t help on color, because, well…as you can see. 
I see you use RT, so my dt edits are of no use, but I couldn’t help from playing with it anyhow.

This looks amazing, especially the crisp whites and blues. Can you detail out how did you achieve that?

Here is what I did:
- Downloaded your original RAW file and RawTherapee settings
- Disabled noise reduction
- Rendered a PNG file, taking all other settings intact
- Loaded the PNG file into Upscayl, which is a local AI tool for image upscaling, applied the default “Upscayl Standard” model and 1x scale
- 1x scale might seem pointless, but it isn’t: it’s an effective but slow denoiser
- Converted the result to JPEG and uploaded - see below.
The AI warning applies - but it was running on my laptop.

White balance was rather tricky, probably fluorescent light of some kind. Great sensor dynamic range test.

Now this was an unsettling learning experience.
I don’t think the noise is a problem - I’d be very happy with just the profiled noise reduction from DT, but I experimented a bit with contrast equalizer, too. Seems fine.
But everything else, oh my god.
On one hand, I’d be very happy to just have this photograph and print it with minimal editing. But of course, I needed to try to “improve” it. Whatever I tried to to do to the colors, I was to choose between sickly green and fantasy purple, or a strongly desaturated or faded look. And that guy in the background! I tried, for the first time, to do more with the retouch module than just heal a dust spot, but gave up, all I did was making it worse, and so he is allowed to stay.
This is a bad edit, but after these hours (plural!) I am posting it, if only to to document what doesn’t work.
