The special feature here are the dark watercolors "Higgins Black Magic INK!" Samuel's face needed more depth, but didn't need to look so dark until he looks like a silhouette. So I made sure the highlights on his face was evident and the darker areas showed up... like the edge of the sideburns on the left side of his face, facing you. I applied ink. The darkest line where his lips meet-- yep, used ink there too. And his eye pupils, along with a bit of shading, I used ink there as well. His hair? All inked in with a paint brush. While I had the paint brush out, I also highlighted the light reflections blurred on the gun, highlights on his t-shirt, and some in the whites of his eyes. Let me tell you, his hair alone makes this tutorial ADVANCED! Then I sprayed again to make sure his hair, gun, hand, & shoulder edges would not smudge while adding the background.
