Okay, I might as well give a few pointers.
SKIN: First I find a peachy colour, and go over the skin with it in Color. Then I make that peachy colour a little lighter and go over the skin again--this time with Multiply. For Color I used a hard-rounded paintbrush, for Multiply I used a soft-rounded paintbrush.
EYES: For the eyes I usually convert them into black and white(from the skin colour) and do a layer of blue in Color, then the same with Multiply. Then I do the black of the eyes with ,Multiply wiht the opacity 100%.
HAIR: I usually choose a browny type of colour and go over in Multiply.
CLOTHES: Depends on what looks good.
MAKEUP: For the lips I find a pinky-peachy colour and go over in Multiply twice. For the cheeks I find a peachy colour and go over in Multiply with a soft-rounded brush.
Hope this helps.
