How do you draw faces?

well I usually start off with a nice round circle......then I dot 2 eyes and a mouth and make an upside down v for the nose.....hope that helped....

Portrait drawing is IMHO the highest genre of realist and representational drawing. The most effective way to begin a portrait drawing is by first establishing the outside shape of the head and then fixing into place the major landmarks such as the brow ridge, base of the nose and width of the face.

Portrait drawing requires a skill level that really needs to be both acquired and hone.

A site that I use to get free portrait drawing lessons is http://www.artacademy.com. I'm sure one of their lessons will get you started on the right track.
