If you want to discover the secrets of drawing realistic pencil portraits you really need to visit this site: http://pencilportraits.toptips.org/
These drawing lessons, both throughly enjoyable and productive, go well beyond casual sketching: students learn to observe minutely the details of any given face, to see what is, and what is not, before them, and how to translate what they see into what are after all just pencil marks on paper.
I highly recommend it for both the experienced and the inexperienced artists alike.

You know it will be sloping down rather steeply, yet be concave up, so if you draw something like what the curve y=x^2 when x=-2 , but on your sketch, put it at (5,3)
