Start with a contour drawing on your airbrush board.

Look for an optimum curve and position the portrait template to spray on the first shading with transparent black.

Change to the next curve to further develop the lip contour.

You can see here how the portrait template optimally rests on the lower lip edge to prevent overspray and to contour the shape.

Working freehand, the lips can now be lent greater volume through the correct positioning of light and shade. You should also carefully spray in shading below the lips.

The portrait templates are also useful when it comes to indicating the creases of the mouth.

The intermediate results are apparent here. Light structures are developed on the upper lip with the airbrush. The eraser pencil creates further highlights. Light and shadow around the mouth are also created freehand in thin layers to give greater shape to the mouth.

Additional skin structures created with the eraser pencil and little light details with the electric eraser or scalpel make the overall effect even more realistic.

Start with a preliminary drawing to create this smiling mouth.

Look for a suitable curve on the portrait template and spray in the first contour between the lips and mouth cavity.

Then move further with the template and shape another lower lip area.

Use a somewhat straight section of the portrait template to indicate a tooth lying in the shadowy area at the rear.

Here's the intermediate result after a few minutes.

Now shape the area from the gums by covering the upper lip area piece by piece with the portrait template.

Then use another curve to shape each tooth individually, tooth for tooth. Always spray only a little paint in short runs on the template edge.

The portrait template even offers a solution for creating difficult shapes!

Spray the lower gum as well with the aid of the template.

The intermediate results are apparent here.

It is now time to continue with the coloured area around the mouth, or the coloured connection between the mouth and facial surface. The upper lip also receives additional colour shading and structure.

Glossy highlights and structure are created on the teeth with an electric eraser.

The shape of the lower lip is now developed.

The highlights of the lips were created with the eraser pencil and electric eraser. The outer area of the mouth is developed further with light transparent layers.

Further details such as laughter lines on the face and nostrils can also be traced with the portrait template and then optimised freehand with the airbrush and eraser pencil.

Here is the finished motif.
