To draw Leonardo Dicaprio as Jay Gatsby, we should first sketch in some basic construction lines. Use a 2H or hard pencil so that the lines are easy to erase when we ink later on. Sketch the basic shape of the head and upper torso. The head should have the crisscross construction lines of the face, but the lowest line (the mouth line) should be slightly high since he will be smiling. Draw the shape of the right hand outstretched towards us, but you don't need to draw fingers.
