I'm continuing with the monochromatic color scheme. The clothing is all variations of Pure Black, Dusky Skin Shadow, Dusky Skin, Dusky Skin Highlight, Weathered Stone, and Leather White. Without a lot of color variation I'm trying to add some freehand details to his clothing for some additional visual interest. I'd like to continue that when I do the pants... but I'm not quite sure what to do. I did a quick test with a checkerboard pattern and another with vertical stripes... but it seemed a bit too busy/loud. He's a sneaky assassin so he shouldn't have on anything too flashy. I could maybe live with some thin stripes. At this point I'm leaning towards a stripe detail down the side of each leg. Something similar to the design on the hood (2 stripes with some design in the middle). Or I could try something more graphic instead of an abstract pattern.
Here's an even bigger close up of the face. I think it's easier to see the color in the cheeks and some blue in the lips.
