Meanwhile I lived in San Diego I sketched around my neighborhood and the city in my free times.
Sketching and drawing by hand is the basis of any other technique. Being able to quickly show what you have in mind, to create a perspective composition full of personality on a blank paper using only three different pencils is something worth encouraging.
The hand makes the brain think better, and solves problems in an instinctive, easy way, especially in a preliminary phase of work.
Hand drawing is an exploration, a birth or evolution- layer by layer, trace by trace, and a way which helped me understand this amazing city.
