How To Paint An Ultra-Realistic Pair of Human Lips
Step 5: Adding The Shadows
Establish the left side as the shadowed side by adding Alizarin Crimson and Cadmium Red Light. The lip area should still be wet, which will make your lines fuzzy, but continue to follow the lines and curves on the lips. Soften the edge around the lips with clean water and the size 2 round brush, then with the same brush, mix Dioxazine Mauve and Cadmium Yellow Extra deep for a dark brown to paint the inside and corners of the mouth, around the teeth, and the line where both lips are touching.
