I thumbled on this blog from Tom Richmond, where he explains how to make caricatures. The lessons are great! There's only 2 of them now but there will be more in the future.
I loose drew some copy's study's of the drawings where he explains some stuff.
After I had read the 2 lessons I started to do the exercise from lesson 2. After that I tryed to do a caricature of an actor without looking at other caricatures. Is he recognizable?
