Hello and welcome to my shading tutorial.
I must say, first off, that I am in no way the best, and my method is even looked down upon by "real artists" but I am happy with the way I shade and this tutorial is merely a step by step process showing how I, personally, go about shading. :) Many artists have different techniques and it's always a good idea to try different methods, so take what you like from my tutorial and add it to what you already know.
The images shown below the text are shown at 800x600 pixels. Click the image to be shown a larger resolution. :)
I am starting with a pre-drawn image. I am using Paint Tool SAI, image size of 355 x 874 pixels. I normally work on a larger canvas, but I chose this image simply because it was a recent work that wasn't already shaded.

If you take a look at the image above, you'll see that I have my layers already set up and named accordingly. The base color layer is a layer that I use to "clip" my other layers too. It's always one solid color, in this case, orange. I put all of the markings and other colors on another layer, titled "Extras". The red line on the left hand side of the layer means that it is "clipped" to the base layer. This means that no matter where I draw on the "extras" layer, it will only color over the areas that are colored on the "base" layer, in this case, the orange.
I have the pen tool selected, mostly default settings. I lower the density a little bit. I choose a gray-tinted color for the shading, in this case, green.
