If you studied head construction by Andrew Loomis you'll understand the issue I'm talking about in this post.
On page 21 of Drawing the Heads and the Hands Loomis describes his method of constructing a head using analogy with a ball and a nail. It looks very simple and easy to understand...until you actually start constructing a head yourself.
My problem was with the "ear" line. I could not figure it out.I gave up and moved on.
A few days ago, I was reading a ConceptArt forum and came across the post called "How to correctly establish ellipses using Loomis head construction?" Needless to say how happy I was to discover that someone had asked my question. But the real treasure was ahead. There was that JohnB who shared his method of establishing ellipses. It was answer to my prayers! Thank you, JohnB!!!

JohnB has his own blog, interesting and very informative.
And this is John's tutorial I recreated:
1. Draw a cicle and mark the center (A)
2. Think about position of the face: is it looking up or down? turned to the left or right? Add a point (B) to where a "brow" cross will be
3. Connect A and B
4. Draw a brow line as per step 2
5. Add a line running through the center that is parallel to brow line
6. Add tick marks perpendicular to the line in step 5
7. Draw ellipse that starts and ends at tick marks you did in step 6 and passes brow point (B)
8. Draw a middle line (face line) that is tangent to the ellipse you just drew. This line determines the tilt of the face plane. This line and line you drew in step 4 are what Loomis calls "the all-important cross on the ball".
9. Draw a line that is parallel to the middle line from step 8. This is what Loomis refers to as a nail in the ball
10. Add tick marks that are perpendicular to the "nail" line
11. Draw ellipse that connects tick marks and goes through the brow point. This is a brow line.
12. Add tick marks that are perpendicular to AB line
13. Draw ellipse that connects the tick marks. This is "ear" line.
