Step 14 In Photoshop, open texture layer.psd from the Download Zone. Select All, then Copy and Paste it into your design. Set the blending mode to Screen and the opacity to 23. Adjust until you’re satisfied.

Step 15 Select the Burn tool and paint over the edges to give it some shadow. In the Options bar, set the Range drop-down menu to Midtones and add some shade to corners. Think about basic shading when doing this.

Step 16 Finally, select the Dodge tool. Set the Range drop-down menu to Highlights and add highlights in the eyes, cheeks, and certain corners to make them pop out a bit more.
