The pictures with points are not substantial different, they shall visualize what the marked points are for.
Start with the eye. I placed the points in the succession of how good I could imaginate their places.
Then the bridge of the nose and the forehead.
Mouth.
Chin.
Shape of the face's 'rim'.
Root of the nose.
Cheek points between nose and 'rim', well placed to get a reasonable net of triangles.
I build the triangles in the succession of how good I could image their places as I did before with the Points.
To get an early impression of how it looks I shifted the different parts relating to their heights (the face taken as a landscape). Only estimated, not absolute places!
The 3D-VIEW shows that there were not enough points in the area aside/under the mouth; I had to integrate some more.
What you cannot see: the half face had been doubled, mirrored (flipped normals) and after some tweaking of the single points with the move tool and turn tool. The second half has been deleted and through doubling, mirroring etc. replaced, to get a symmetrical shape.
