The document provides instructions for creating a portrait illustration in layers. It describes creating a "Skin" layer filled with skin color, then a "Skin Lines" layer to add linework contouring the body and facial features using the Pen tool. Details like hair are to be marked out and filled with black, with thin lines added for individual hairs. The process builds up the illustration piece by piece in separate layers.

Focused on
line quality

19. Reference Photo with no with
background cropped, and new
background pasted in layer underneath.

21.  We’ll build up the portrait by creating
blocks of skin, then adding in
linework, clothing and the details.
First, create a new layer in the
Layers panel and call it ‘Skin’.
 Select a color for the skin –create a
vector outline around the body´s
contour. Don’t include any clothing
or hair that extends beyond
the shape of the body, they will be
covered with others layers later.
 Next, fill the shape with the skin
colour. Open the Paths panel and
click on the Fill path with the
foreground color button at the
bottom. Hide this layer, so we can
use the photo to create the linework.

22. Line Work
 Create a new layer, called ‘Skin
Lines’. Select a dark brown color,
and a brush with a 3px radius. We
can use the path created for the
‘Skin’ layer to create linework
around the whole body and face. In
the Paths panel, click on Stroke
path with brush.
 Use the Pen tool and the Stroke
path with brush command to create
the lips, nose, eyes, jawline,
eyebrows and any other clearly
defined features. To create thinner
lines, simply lower the radius of your
brush before using the command.
Use an Eraser with a hard brush to
fix any untidy line shapes.

24. Next, use the
Pen tool to mark
out the outline of
the hair and fill it
with black. Use a
thin brush to
add fine hairs.
