06. To push values even further, introduce some highlights on the face. You have to be more careful here, as you don’t want to over-use highlights. Shadows are always more important than highlights in defining form. Overusing highlights will make your image look plastic and fake, especially in regards to skin. Try adding subtle highlights to the forehead as well as the nose, using a lighter variation of the mid-tone colour.

07. Once you’re happy with the values, create a colour palette on a new document to help with the painting – you can drag it to the corner of your image as well, which makes things even quicker. Take your time and experiment with your colour palettes – rushing this step will harm the image. In this case, Patsouras chose very pale yellows for the highlights, as well as warmer magenta tones for the shadows.

08. Softening out the face can help it look more realistic. Using softer-edged brushes, blend in the harsh edges to give the face a softer look. You don’t want to overdo this, however – overusing soft brushes can give your image a plastic, lifeless look, so try to find a good balance. You can easily control the hardness and softness of brushes by right-clicking (Ctrl + click) anywhere on the image with your brush activated.
