Skin retouch with new retouch module in Darktable 2.6

Hello friends, here it is my trial of new retouch module in Darktable 2.6
This is crop from original image

This is result

Points to make attention to,

  1. Select right number of scales: residual scale should not be completely blurred, it may contains some details
  2. Use blur selections on residual layer with high blur radius, blur small areas instead large ones
  3. For details scales to remove imperfections it is better to use patch tool, if the area is large use blur tool with low blur radius
  4. Large imperfection is better to remove with patch or heal tool on composite scale
  5. Bilateral blur produce strange color patches and stripes, after some trials I decided not to use it at all on any scales. Probably it can be fixed by developers.

Here scale 5,

Wow, impressive results. Skin retouching with the retouch module seems to be much more easier than in Gimp or Photoshop.
Since I did not use this new module before this thread reminds me to take a look at this module.
For training purposes I found some free portrait RAW files:

After watching several tutorials about frequence separation and wavelet decomposing on YouTube and experimenting around with Darktable and the wavelet decomposing from G’Mic in Gimp I finally think I got the basics now.

I took a picture from Play RAW and was able to improve the skin:

Moreover I hit the screen record button while I was working on the image and added subtitles afterwards:
