They say the eyes are the window to the soul and when you’re drawing animals, nothing brings a portrait to life more than a believable, soulful eye. But eyes can also feel intimidating: so much shine, colour, and tiny detail packed into one small space!

The good news is, with a few simple techniques, you can build up depth, drama and sparkle in any eye, whether you’re drawing a dog, cat, tiger, or even a tiny bird.

Here are my top tips for capturing that magic:

1. Start with Structure

Before diving into colour, lightly map the basic shape of the eye and the eyelids around it. Think of this as scaffolding – it gives you the right proportions so the eye doesn’t “float” without context.

2. Use Dark Blues Instead of Black

It’s tempting to reach straight for black, but using a deep indigo or dark sepia creates a much more natural look. These shades give you richness and depth without flattening the drawing.

3. Layer Softly and Slowly

Eyes aren’t made in a single heavy layer. Use light, circular strokes to build up colour gradually. It’s a gentle “one step forward, two steps back” process: add colour, blend, then add more layers. That’s what gives eyes their glassy smoothness.

4. Blend for a Glassy Look

To mimic the shine of the cornea, blend colours together until they connect seamlessly. Think of it as polishing glass – the smoother the surface, the more realistic your eye will look.

5. Balance Highlights and Shadows

Most people focus on the bright catchlight and yes, it’s important, but shadows are just as crucial. Without them, eyes look flat. Notice where the lid casts a shadow or where the iris dips into darkness, and really lean into those areas.

6. Keep Highlights Subtle

Not every animal eye has a glaring white highlight. Sometimes the catchlights are soft or tinted with colour. Let your darkest tones do the hard work, the contrast will make even a muted highlight stand out beautifully .

7. Enjoy the Mindful Process

Eyes are small but mighty. Don’t rush them. The mindful layering of coloured pencils,  watching the drawing slowly come alive,  is part of the joy. Allow yourself to get lost in it.

Remember: every eye you draw is unique. Don’t worry about making it identical to the reference photo. Aim for “believable” over “perfect”  and you’ll capture the life and character that really matters .
