All of this makes it easier for beginners to enjoy digital painting without losing the traditional watercolor experience, while also making expressions feel alive.

Steps

Sketch: The Fondation of Expression

1. Build the basic shapes

Every face can be broken down into simple forms:

- Circle or oval = for the skull or head

- Vertical center line = to divide the face left and right, helping keep the symmetry

- Horizontal lines = to mark the position of the eyes, nose, and mouth

- Square or trapezoid = for the jaw or chin

2. Define the Basic Proportions

- The eyes are usually positioned at the vertical midpoint of the head.

- The tip of the nose is typically halfway between the eyes and the chin.

- The mouth is usually about one-third of the way down from the nose to the chin.

Before adding details, focus on capturing the facial expression using simple lines and shapes:

- Use curved or straight lines to reflect the expression (smiling, frowning, etc.).

- Use boxes or curved lines to map the position and length of the eyebrows, as well as their distance from the eyes (adjust the curve based on your reference photo).

- Sketch the eyes as simple boxes to build the initial structure (remember, the space between the eyes is about the width of one eye).

3. Capture the Expression with Simple Shapes

Once the basic shapes and proportions are “locked in,” start adding:

- The shape of the eyes, nose, and lips

- Hair and other accent

Don’t worry about the details yet—focus on capturing the overall impression first.

4. Develop the Final Details

Start adding the details.

Expression Tip:

- Pay attention to small details: a slightly raised eyebrow or subtle tension in the lips can dramatically change the overall expression.

- Experiment with different camera angles from your reference photos to better understand the depth and nuances of the expression.

Shadows and Highlights: The Soul of Expression

Shadows and highlights help “tell the story” of emotion. And these are the steps to show you how impact these part to achive stunning results.

1. Base Color

- Create a new layer under the sketch.

- Use “Opaque Watercolor” for skin, hair, clothes and eyes.

- Work on separate layers for each element to maintain better control.

Expression Tip: Choose base skin tones depending on mood. Warm tones (peach, pink) for cheerful looks, cooler tones (pale, bluish) for calm or melancholic expressions.

2. Shadows

- Add a new layer in Multiply mode and use “Transparent Watercolor”.

- Apply light pressure to gradually build shadows.

- Focus on darker areas: under the nose, eyelids, under lips, and the side of the face opposite the light source.

Expression Tip: Direction of shadows changes the emotional tone. A strong shadow across the eyes can create a dramatic, mysterious look, while softer shadows give a gentle, friendly vibe.

3. Blush

- Use “Transparent Watercolor” in Multiply layer.

- Lightly brush pink or red onto cheeks, nose, lips, and ears.

Expression Tip: Blush placement is powerful. High blush near the eyes = shy or flustered. Subtle blush on cheeks = warmth and friendliness. Combined with eyebrow tilt, it can instantly change the emotion.

4. Details

- Glasses: Draw frame, shadow, and lens reflections on separate Multiply layers to prevent mistaken. Begin adding eye and eyebrow details at this stage.

- Hair: Paint larger shapes first, then add light texture lines.

Expression Tip: Hair movement can support expression—loose strands for a carefree look, neat lines for a calm personality, sharp angles for intensity.

5. Highlights & Finishing Touches

- Add small highlights on eyes, lips, or hair using pencil or simple brush.

- Try “Running Color Edge Watercolor” for soft, bleeding effects.

Expression Tip: Eye highlights are key. A bright sparkle makes the portrait lively, while a faint or shifted highlight can give a thoughtful or melancholic look.

Conclusion

Portrait drawing is a journey, not an instant destination. With the Classic Watercolor brush, beginners can experience traditional watercolor vibes while enjoying digital convenience.

Most importantly, focus on expressions. Every tilt of the eyebrow or curve of the lips adds emotion to your art. Don’t stop at one drawing—try the same character with multiple moods, and watch how watercolor enhances each feeling.

Now it’s your turn to capture not just the face, but the emotion behind it.
