I like to start my drawings at the center of the paper, usually in the eyes if I'm doing a portrait, and keep on working from there, I work by sections, each by adding material to the paper and see how I can create the illusions I'm looking for, my style is mainly realism, however, even though I may put in a lot of detail into the drawing, sometimes I would try different kinds of techniques on the paper with the respective material to satisfy me and the views eye. It all depends on what the drawing is about, what I'm trying to communicate, and how I wanna finish my piece.
