Drawing portraits is one of the toughest tasks out there. Unlike drawing objects, drawing portraits require a lot of effort. There are certain tips you can follow.
Look at the shapes: The best way to start is to simplify the portrait and figure out shapes. The face will be made up of lot of circles and triangles which can help you get a better image.
How the features align: Observation is the key. Draw vertical and diagonal lines on your reference photo to figure out the alignment of the features.
Draw lines to measure the distance between the features: You can draw lines to figure out the distance between the nose and the ear, the lips and the ears and so on. This helps you to get the face right without overdrawing the features.
