Here is a before and after shot of a life drawing done from a model. I hardly ever finish a whole drawing with the model sitting in front of me. I like to have some really dark areas, and those take up a lot of time that could be better spent on other areas of the drawing. I think it’s good practice to figure out tones intellectually from time time to time, instead of only observationally.
