Line eye with metallic gold liquid eyeliner.
Used: Kat Von D in Romantico

Prime eye with Mac shadestick in Butternutty

I used Mac pigment in Rose Gold
for this look I wanted bright metal so I foiled this. No not (X+2) (X-6)
Foil as in taking a drop of water or eye drops and wet the brush then dip it in the pigment patting it onto the lid.

Along the bottom lash line I rimmed it with Mac Museum Bronze

Apply Mac Rushmetal into the crease bledning well into the foiled pigment

On the browbone add Jardin aires pigment all over. (Watchout for fallout; those pesky flecks of metallic pigment that falls under the eyes)
You could end here to have a dramatic look or continue to the next step for more authenticity.

Then I used Kat Von D liquid liners to create tiny cogs and gears for more emphasis
