Hi, Zizka! By coincidence rescently I was trying to figure out cross hatching, so I am a beginner at this, too. Here is what I could find applied to your drawing.
First thing you probably already know - your lines should follow the surface of the form. When plane changes so do your lines. And face has a lot of form breaks that you have to analyze before starting shading. For that I would recommend to study head anatomy, maybe not very deep - just to understand wtf are all those bumps and turns. Also there is a lot of shemes and 3D models with simplified head planes useful for constructing when drawing. Like this https://www.artstation.com/artwork/GX3Ax1
The hatching itself. As I understood we find a central axis and relative to it build a symmetrical system of lines. So when you choose a certain line pattern on one side, it should be the same for the other one or else will be a chance that three dimensional effect won't work.
I wanted to point out that eye balls are spheres and can be shaded the same way as anything spherical
Hope it was hepful in some way!
