Traditional Drawing / Digital Drawing

 Drawing with Genius graphic tablet, in Ps CS 2

 Traditionally drawing, pencil on paper

There is a difference between the real drawing line and the virtual one.
In Ps, the first drawing, lines are more shaky, that's why there are much more lines, to highlight the appropriate shape. But it's still a nice looking drawing, not a poky ugly one, though you are struggling more to do it. There are softwares that help you draw real natural lines, so no more hard lining in Ps:) which is more helpful for graphic, photo editing etc.
