Actually the figures are the 'lazy' way to paint. 3 rules:
#1 Color has to be correct! Nothing worse than yellow skin tones. (jaundice?)
#2 Enamel for base colors and thinned for highlights, even dry brushed on nose.
#3 Acrylic wash for deeper shadows like eyes, creases in face and around nose. Hull red works well. Avoid black even to darken hues,
Oh and you really don`t need `Flesh`color, white + red = pink, darken with red-brown or flat military brown.
Easy breezy, I came up with new kung-foo for eyes and will see if FSM is interested in that!
Last but not least to get skin `shine` after clear flat is sprayed to flatten clothes, brush your forehead a few times. Apply that natural `grease`to your figures skin! Also works great for shiny belts ect. Pencil crayons and lead pencils work great for adding highlights to uniforms, badges and zippers.
