I'm struggling with head turns, what's a good book that will help with the subject?

I'm currently going through Loomis's Drawing the Head and Hands and Burne Hogarth's Drawing the Human Head. While the latter has some really great methods on dealing with how much cranial mass should be shown in the back based on the amount of turn in the pose, I am struggling in figuring out how to properly place the contours of the foreshortened forms of the eyes, nose, and mouth barrel.

I specifically struggle in placing eyes based on head turn. I have seen many diagrams showing axis lines hinting how to place eyes on a turned head (like pic related) but my heads just don't turn out that way. There is some bit of knowledge I'm missing in order to check my eyes are correctly placed. Eyes are easy in a purely front or side-view but as soon as the head turns and the nose starts to overlap and the eyes themselves foreshorten, everything falls apart.
