alright, here tones.
You can clearly see the hair tones, darkish purple, dark blue to light blue.
then for the skin dark blue, flaring green and pale yellow green.
Basicly. darktone=blues-midtone=greens=lightone=yellows
Basicly, lay down your midtone first, then the darktone then the lightone then the highlights( which is basicly just white, but not all the time)
In some painting cases, you but the darktone first.
But you get the idea. Basicly follow that and make sure you have opacity, not 100, have the edge slightly blurred. Remember that.
Take note, add tattoes and stuff BEFORE highlighting, but also make sure to keep the tattooes lighter tones aswell so it doesnt look flat.
