Touching Up the Highlights
Increasing the shadow areas will make the illustration look a little dark. Add another layer and add light areas to balance the illustration out.
1Click [New Raster Layer] on the [Layer] palette to create a layer.
Double click the layer name of the layer you have created and change the layer name to "Luster of hair".
2While the "Luster of hair" layer is selected, click [Clip at Layer Below] on the [Layer] palette.
The "Luster of hair" layer is clipped to the "Hair" layer along with the "Retouch hair" layer and a red vertical line appears next to the thumbnail. In this case, the "Luster of hair" layer is clipped to the drawn area of "Hair" layer, not the "Retouch hair" layer immediately below the "Luster of hair" layer.
3Select a yellowish white on the [Color Wheel].
4Using the [G-pen] sub tool of the [Pen] tool, draw highlights along the hair.
5Add light purple highlights in areas where light would be reflected, including in the shadow areas.
