A drawing skill

I always wanted to learn drawing. A few days ago, when I was watching the additional material in comics Hellboy, where were drawn the sketches with different characters, I decided to try one more time. I began to look for simple drawing books and I handled to find some books by a famous American artist where he had been teaching the simple ways how to draw with a pencil.

All that you need to start drawing is just to be able drawing a circle, not necessarily ideally even. Then the author showed how to draw funny faces from a circle and then talked about human body proportions and what means the perspective and how to understand it.

I hope, this time I can advance a little more on the way of drawing something with a pencil. But If I even can't, I'm going to spend my time with pleasure anyway.
