Use Light Neutral Colored Eye Shadow
You can make your eyes appear big by using neutral and light eye shadows. And follow the rule of contouring. Use light colors at the center of the eyelids to bring them forward. Take some product with a brush and tap the excess off. Now gently apply at the center of the eyelids.
You can use shimmery or matte finish shadow; it doesn’t matter as long as it is light in color.
