Where do I start studying shaders?

Sorry for this question, I know, a lot of people hate questions like that, because probably there is another post like that, but, I don't know where I can start, I don't even know if Shaders are what I'm looking for, I'd like to change the shadows of my game, something like 'Final Fantasy Tactics: The War of the Lions' CG's, I know this is not easy, but I'm not an entire noob, I know C# and it's not my first game, but I don't know the name of the technic or whatever what I'm looking for.

I read these articles, but don't looks like what I want, so I don't know if Shaders are what I need study:

It's hard to look for someone when you don't know his name, right? Again, sorry if there is another post exactly like this, I don't know where I can start.

 

Shaders are what you're looking for, that and NPR rendering, aka "Non-PhotoRealistic" rendering. The look they're using is sometimes called hatching or cross hatching shading. You can search online for NPR shaders and you'll find several examples (not using Unity) of this effect, but there are also some on the asset store, this being the most obvious one: https://www.assetstore.unity3d.com/en/#!/content/40360 Some of the other "toon" shader assets also have options to enable similar looks.

 

Thank you, I'll study NPR and shaders, now I know where to go
