To do this I used Snazaroo face paint in white and applied all over the face. Then with any black pencil liner I drew in the eye sockets, cheekbones and mouth and then coloured in using a gel liner. To colour in the eye sockets I applied gel liner all over then applied black eyeshadow to lock in the colour.
I then marked out where the teeth should go in black liquid liner ( can be used with gel still) and then coloured in the teeth with a white liner pencil.
I then proceeded to shade in the details using a blending brush and then used the White liner again to highlight specific areas.
And that is pretty much it :)
