@Bxbyyxda1 Tut for shading!
First start with your base colors
Then I use purple to color in spots I want to use shading (ON A DIFFERENT LAYER THAN THE SKIN, AND USING CLIPPING MASK TO MAKE IT EASIER) The darker the skintone the darker the purple
Then you do to layers and click on the shading layer, then scroll all the way down and low the opacity of that layer to your liking
Then the end should look like this!
