I was uploading the shots attached, and confirming the technical terms of the orientation of the head in portraits to put in the keywords.
So the standard terms are:
"Full face" for straight on (as in the image above)
"3/4", where the head is turned slightly away
"Profile", where the the head is shot side on (as in the image on the right)
This site shows it well: http://portrait-photographer.blogspot.com.au/2009/04/views-of-face.html
