Quick sketches of cliffs ...To what end? The reason is that I have to prepare the background for a didactic job full of birds ... in these cases I have always worked in pencil trying to draw many details as possible for the customer. After two decades of this procedure I decided to change record, I thought it was fun creating simple and quick sketches, to put in a little 'more of the "artistic" and a little' less of that didactic.
