Lmao that caption. Anyways, I use a program called Krita (idk if it’s similar like CSP, but it’s really close with Photoshop) when it comes to shading and digital art in general. What I would do is make an layer and get a soft brush. I would get a color darker than the original color, for example, the color white would be a warm gray for shade color. Once I get that, I decrease the opacity below 50%( or a lot lower if needed) and color it on the new layer. Then I would switch the layer to a filter called multiply. (I usually use many kind for different layers, but since you’re new, I’d suggest trying out multiply first to get used to the filters).
The filters are found here:

CSP (Sorry it might be an outdated pic)
If you feel the shade is too thick, you could always change the layer opacity as well. Tbh I always do that since I’m too lazy to restroke a perfect stroke.
And the results usually looks like this for me:
You can also do this with highlighting as well (as you can see on my alien’s bulbs)
I wish I could show you a better example, but my pc is updating and it’s almost midnight where I am lol.
Here is some of my stuff, tho I am still new so sorry.
Some drawings I've done. Still not the best at shading and the straight forward looks.
Still learning body shapes, but since this one came out so well I thought I would share it here.
