I've been trying out several different face styles lately (stay tuned for more fun projects). I find that some look good in the drawing stages, but not so good once painted. Others, like the one above, look sort of dull and unattractive in the drawing phase, but once the ink lines are added and color put in, they really start to pop.
Here's a peek at some of the faces I worked on today. On the bottom left you can see my Tiffany girl take shape...
Outlining with a Papermate Flair Pen
Generally I paint the skin tones first.
Then I go in and add all the rest of the color.
The last step is my favorite. I go back in with Micron Pens and Prisma Colored Pencils and give each girl a little more detail and personality.
