All the sketches I made until now followed, more or less, what I learned on Andrew Loomis "Drawing the Head and Hands". I'm really satisfied with results I had, but in the same time I feel that's not what I'm looking for. I know I need a nimble way to work, a looser way to work. I think Charles Reid contour drawing method could be suitable for the purpose. I can't do anything but give it a try! This is the first attempt.
