You didn't respect the contrat , you just had to touch the contrast (just remove) , it looks more like an HDR (the photo doesn't look very natural anymore), the modification of the levels is to my taste more subtle, it rebalances the colors, and attenuates the dominant colors which darkens the photo (similar to the first time has contrast)
The tutorial shows the development of this technique.
My apologies then @Christophe Berche , so the target is to achieve natural image ? without much colour and contrast ?
