Take your dark eyebrow pencil and define the natural shape of your brow by making an outline
Fill in the outline with dark eyeshadow using your angled brush using a stroke by stroke technique so it doesn't look too harsh
Use the foundation/concealer to define the shape and clear up any mistakes. I've used a lighter foundation to add a contour effect
Blend the inner brow so that it's not harsh and less square
Don't worry if they're not symmetrical, just follow the natural shape and make your face POP!
