Well, not a real tutorial, just a walkthrough, actually.
Narsha and Zaoll face-up:
- First step defines the color areas of the face, where which color goes, using the lighter shades of each tint. I also usually define the mouth line at that stage unless I forget it^^"
- Second step is for accentuating colors, use darker and more saturated variations, start working on the skin texture and define the eye-brow shapes. I usually try the eyes on at that point in order to make sure the facial expression is coming out fine.
- Third step comes with details: more skin texture, lashes, mouth details, eye-brow details, while the darker parts of the face-up get more dense color with extra layers of pastel.
And then a layer of gloss or two, and here we are :)
