If you are going to be painting flesh tone mighr I add my prefered method. I use a lot of differenr techniques but mostly play it by ear. My approach with both light skin and dark is the opposite of most people. I work backwards from other customizers. For fair to tan skin, I start with a light base. Then do a wash with a shadow tint. These are all Testors MM by the way. After the wash drys I drybrush with a warm tint and repeat until it is evenly blended. Then I add a very small amount of light to the warm and drybrush leaving the area of the previous warm around the edges blended. Then I add a little more light to the warm and hit the higher areas in the middle of the muscles again until it blends in. After that, I get a toothbrush and dab it in a mixed red and warm tint. You can go darker, lighter or even brown. I use a piece of paper and flick that paint against the paper until I get a fine even mist. Then I use the same method to add blemishes on the skin. Too much splatter and he has chicken pox or worse. Use light base to paint any veins invat this point. I then thin my paint a little more than usual, I normally only slightly thin on the previous layers, to create a smoother paint to drybrush over parts of the blemishes where it was too much and hit the high areas again. The eye bags/ lids, corners of the nose, and crevice on the sides of the cheeks leading down to the mouth are done with a 50/50 red and warm tint. Then a brown colored pencil is used to add body hair and dark circles around the eyes. 5 o'clock shadow is made by creating a hair pattern on the jaw or bald head with a fine point needle and using oil paint but that's a whole other process. This should all ne sealed at different stages and generously when finished with a matte sealant. My WIP was started from the first warm layer I believe. Dark skin, unless it's really, really dark, I paint with the same techniques except I start with the darkest flesh as a base and work lighter. I know that doesn't sound right but darker skin does not show detail as much. As long as you don't go too light, except veins, it looks more textured and can be added to easier. For adding skin texture you can take a rough sand paper press hard into the plastic on softer parts before painting and nudge slightly to the side. This creates the appearance of pores.
