Part 2

For the yellow lettering, use staggered diagonal strokes to simulate a bronzey-brass effect with 55-154 'Metallic Gold'- Badger spectra-tex range.This will give the letters an added metallic shimmer which will breathe some life into them. Don't worry about being too accurate as we will shortly be going around the letters with black using the stencil again.
Like so...

Now replace the face stencil but this time using black carefully dust in black from the corners of the mouth, but DO NOT make it a solid black, subtlety is the essence here...
The same with the hands, but by replacing the stencil and going around the OUTSIDE this time we are effectively creating the negative space that gives the hand some form.
after the black and yellow use 55-169 'Neon purple'- (Badger spectra-tex range) on the eyelids and on the reflected section of the hair. Rather than a solid black create a texture that is a bit like marble that adds contrast to the organic form of the visage.

Go over the black towards the end of the process with Opaque Black (55-146 'Jet Black'- Badger spectra-tex range). This will tidy up the edges left by the other colours used so far.

Finished!
