Here's an example of a 15 mm sci fi model I painted with the same formula:

It's Vallejo Electric Blue on grey undercoat, followed by blue/green wash, highlight with Vallejo Electric Blue and a second highlight with a little white added.
Face is Elf Flesh, washed with Reiklander flesh, highlight with Elf Flesh and then Elf Flesh + Bone White. Finally a very small amount of red wash on the lips.
Hair is done by painting Royal Purple, purple wash, drybrush Royal Purple and then drybrush Royal Purple with a bit of white in it.
White armour/gun were painted light grey, highlighted with white, washed with Vallejo Pale Grey Wash, final highlight of white.
Base is painted grey, washed with Nuln Oil, drybrushed grey and grey + white, washed in spots with Soft Tone Wash.
Hope this can be of help!
