Step 9: Layering of Paint Colours
The key to making anything look more interesting or even more realistic is layering of colours. I put my darkest shades on first, following the underside of any contours I've created. Then when that has dried, I use a dry brush technique (tiniest bit of paint on my brush) of a lighter shade, lightly dragging my brush along the shapes. Finally, I use an even lighter shade (almost off white) to highlight the most protruding shapes on his head.
