I first went in with a Snazaroo face paint palette and then set each color with a corresponding eyeshadow. I next lined each rectangle with the black face paint and also added some Mondrian details to my nose. For the lips I used lipsticks and outlined it in the face paint as well.
I ran into the problem of how I could paint a line with my eye closed and it would be straight, but when I opened my eye the line would then be curved. I ended up, for most of the lines, just painting them with my eye open. I could have also gone darker on my brows.
