Well, I didn’t really like my processing, either. 
Now that you have told us what you really are looking for, I have processed the image my way. Well, in fact is not fully processed, but instead just a starting point, so you can go wherever you want with it.
You may want to take a look at this noise reduction challenge thread, so you can see how much you can reduce noise, but not without generating artifacts or loosing something along the way.
This is the new profile: _DSC0986-2.png.out.pp3 (11.4 KB) (I’ve used a custom input profile made for my D5100 that I can post if you need it)
I’m not saying that you will like my current processing, but just that you will have another starting point with it.
A couple of comments:
- the Noise reduction tool is activated to just auto-remove chroma noise
- the noise reduction in the Wavelets tools has been applied to reduce the contrast of the very finest details (not really a noise reduction), to hide a bit the darkest pixels
I didn’t look anywhere in the image but the crop you posted, so I missed it. It was due to fringing in the image. Now it is corrected in the current profile, and you can see the result:
The original crop comes from here:
P.S.: if you want to start using the denoise module in the Wavelet tool, you can take a look at this Rawpedia explanation about it. It’s written in Spanish, but you can easily translate it with Deepl, Google translator, or the online translator of your choice.
