In this step, I'm going to teach you how to shade those rough hard darkened spots. This will make you image look more realistic and add some depth to those flat lines. So what we will do is first get out your smudge tool. You can find this tool on your palate. All Adobe Photoshops have this tool. Make sure you set the brush to a reasonable size to smudge your dark areas. After you found a suitable brush size for you taste, set the strength to 54 percent. This will give you more control of the brush. Its a strength mix of hard and light. Once you got this done, we will move onto the next step. ^_^
