Pair of clouds - black and white partial

Following the recommendation of @PavelSku in this article https://ecency.com/hive-131609/@marjuanm/pair-of-clouds-d059e0351a68, I publish a final version of the clouds in the original post, but now using the Inkscape application to select parts and change them to black and white leaving the rest in their original color.

I had already seen this effect in other photographs and the truth is that it looks very showy, so I wanted to try it, to see how it turned out.
