For medium to deep skin tones, you’ll just want to scale up your shadow crease shades to be one shade deeper than your skin color.
Apply a gel taupe eye liner as close to your lashes as possible. For downturned eyes, tilt your shadow up on the ends to give your eyes a lift.
With the same pencil brush, work a little shadow into the outer “V” of the eyes, blending it in towards your lid.
Using a synthetic brush that has been wet (but with all water squeezed out), start tapping your wet/dry (baked) shadow over the lid of your eye.
