Well, it's been a long time and everyone sort of likes my new digital painting so I thought I'd make a tutorial for it (even though it's the same as my traditional shading and my old digital lol)
This will work for Photoshop and SAI as well I believe, just find a brush that blends well, or set your pen pressure on so you can blend. You'll have to try out brushes, but I'm sure there are Digital Oils for both programs.
It's kind of basic really, and not all that detailed, but I hope it's helpful.
The term "Reflective light" here is not used correctly but that's how I describe it! The light that comes around an object basically.
Some useful skin resources

And many more!
On a side note, I probably should not have uploaded this as the image in it is still not complete ohhhhhh, the surprise has been ruin-ed ohhhhhh!
