Do not use black or darkening tool for shading.

It looks like you’re using diversion and re-exposure. If you use another program that makes the sound wiser or blacker. I’ve done this for learning the program at the beginning, but that’s how the images work dirty or too grell. Meanwhile, I don’t use it anymore.

For light color variations and shade use a brush that becomes more transparent to the outside, i.e. has a soft edge and set the opacity somewhat down to, for example, 30%, 50% or 70%, depending on how fine you want to work there.

Then simply take a color from the color selector or directly from the picture with the pipette. Slightly change the hue, which looks much better than if you only change the brightness and saturation down.

Your images become more professional.
