Sketch in large highlights with Mephiston Red , aiming for the areas where light would naturally hit. This step can also be done with an airbrush if you own one.
Wash all of the skin with Carroburg Crimson .
Recess shade deep areas where muscle groups meet. For this I use Vallejo Game Ink Violet , mixed with Lahmian Medium .
Re-establish the highlights from the second step by glazing Mephiston Red over most of the same area.
Add a highlight of Mephiston Red and Kislev Flesh mixed 1:1.
Add fine highlights selectively with Kislev Flesh .
Apply dot highlights of Kislev Flesh and Ionrach Skin mixed 1:1. Add this mix to points, converging highlights and the center of the fine highlights from the last step.
