I have a lot of troubles with that actually, that's one of the reasons why I did this. I usually do a regular circular base with a cross to mark eye line and nose.. Although for this one I used horizontal lines to match the features across the chart.

It would be useful if there was a second chart that instead had the structure (circle & cross and other lines) so that I could see how to set up that structure to get the preferred angle right when doing the face.
