16 Creating ambience
By making the character stand out, ambient light can transform the quality of an illustration from good to excellent; however, it’s important not to overdo this. Otherwise the illustration will lose the focal point because everything is bright. I want to depict the light coming from the sun behind the character, so I add the strongest ambient light on that side of her. I set one layer to Linear Light and another to Outer Glow. This creates beautiful white light and a yellow glow on its edge.
