I didn't use a skin colored pencil in any of this. I wanted to use yellows, reds, and whites to create the skin color. I only used 4 colors; magenta, yellow, white, and black. I changed up the direction of the pencil multiple times to create a layer of color. I didn't want it to be smooth, I wanted some roughness to the skin.
I liked the variety of going back and forth between something abstract as water color and something as real as colored pencil. One, you have hardly any control over, the other you have control over every stroke.
