04. On the ‘hair’ layer, use one of the custom hair brushes we’ve supplied at 60% opacity to start building a base for the hair. Start with darker colours first, because these will show through to the top layers of hair. Build up with a variety of colours including greys, purples and browns. Don’t get too concerned with detailing individual strands at this point – just focus on the general shape and form of the hair.

05. Hide the ‘rough’ layer and start rendering the eyes on the ‘above’ layer – they will start to bring your image together. Remember eyes are 3D objects; you need to shade not just the iris but also the whites of the eyes. The eyelid casts shadow onto the eye. Show light reflecting on her pupil and add a small light line just above the bottom lid to show where the eye’s water pools, and draw in the eye lashes.

06. Looking more closely at the photograph, you’ll notice that the eyes in our sketch look slightly too wide. If you need to tweak any aspects of your artwork and want to avoid redrawing from scratch and losing the work you’ve done already, go to Filter > Liquify and select the Forward Warp tool (W), using the cursor to push the pixels into place.

07. When rendering the lips, observe the form and shadows carefully. Notice as the lips get closer to the corners of the mouth, they lose a definite outline and become much softer. Use an airbrush to avoid any hard edges at this point.

08. Lock the transparency on the ‘skin’ layer (click the chessboard symbol in the layers palette) and use a very light pink with the spot gradient tool (G) on this layer to indicate the main light source on the skin. It’s easier to use a gradient to depict light rather than a brush; it’s much more subtle.
