She started drawing geometric forms on her lips… The result is awesome!
Now draw two lines on both sides of the cupid’s bow and move these lines straight down till the lower lip. This will create little triangles in your upper lip.
Now you can start with contouring lips. Try to be very precise on this step.
At the beginning trace a line that will cross the triangles under the cupid’s bow (as seen on the below photo). Once this is done, contour the curves that are above. Then go for the lower lip line.
