First, slightly over-line the perimeter of the entire lip in the shade Faun to create a base shadow. Trace the shade Grie over the cupids bow and under the center of the bottom lip for enhanced depth. Finally, use Noisette to create definition on the corners of the mouth and cupids bow, leaving the center of the pout bare. 

Use the Lip Brush to buff out and blend, or smudge together with fingertips for a soft blurred finish.
