Hola! I wanted to practice a little skin coloring on this confused ogre in Photoshop.
First I did a fast line sketch, and then I made a black & white shading for the values, thinking the key light came from above right. At this stage I felt he missed something. So I gave him a mustache. But then he looked like a pirate, so I added some tusks to make him more ogreish.
Then I used the fantastic color layer and painted in the base skin color. For the lighting I mostly used the soft light layer, and painted a warm key light, a cool fill light and a cooler rim light. I added in some more color variations for the skin. Especially where the skin was thin and blood would shine trough and there would be some sub surface scattering (ear,nose etc.). This was done with a lot of layers on top of each other, thinking of what was underneath the actually skin. The rest was adding details like veins, hair, highlights.
