My 4-Step Digital Illustration Process

How I bring children’s illustrations to life, from sketch to final texture

As a children’s book illustrator, I’ve developed a process that balances structure and creativity. Whether I’m illustrating a full picture book or creating a single custom portrait, I follow the same four-step workflow. It helps me work efficiently, stay consistent, and keep the artwork playful and engaging.

Here’s a behind-the-scenes look at how I approach each illustration:

1. Line Work (The Foundation)

Every illustration begins with the linework. I start with a loose sketch to work out the composition and energy. Once everything feels balanced, I refine the sketch into clean, confident lines. This is where the character of the piece really starts to shine through.

I keep the lines expressive and simple—especially important when working on illustrations for children, where clarity and emotion matter most.

Pro tip: If I’m working with a client, I often share the sketch at this stage for feedback before moving forward.

2. Flat Color (Setting the Mood)

With the line art in place, I move on to flat color. This stage sets the mood and helps define shapes and forms. I pick palettes that feel warm and inviting—think soft pastels, rich earth tones, and the occasional pop of bright color for playful energy.

Color can completely shift the tone of a scene, so I give this part extra attention.

3. Light & Shadow (Adding Depth)

Adding light and shadow brings everything to life. This step helps the scene feel grounded and gives dimension to characters and objects. I aim for gentle contrast—nothing too harsh—so the final illustration still feels storybook-soft and approachable.

Even subtle lighting choices can tell a story, especially in a children’s illustration.

4. Texture & Final Details (Bringing It to Life)

The last step is where the magic happens. I add texture to backgrounds, clothing, fur, or hair—anywhere that could use a little extra charm. I also refine details like facial expressions, soft gradients, and tiny flourishes.

This final polish helps the piece feel more finished and gives it that warm, handmade feel I’m always aiming for.


Why This Process Works

This 4-step process keeps me organized and focused, no matter the project size. It allows for feedback at the right stages and gives every piece a consistent, polished finish.

I’ve used this workflow for children’s books, editorial pieces, and even handmade greeting cards. Over time, it’s become the foundation for how I work and the reason I can balance creative storytelling with reliable delivery.
