In an effort to try out darker skin tones, I give you these faces.
All I can say is, ick. The ick color of her face above is accentuated by the weird background color as well. Oh well, I tried.
This one is a little better, but I don't know why her neck is colored so differently. I do like how I did the shading, though. The cheeks are a lighter color that the face. I like that rather than relying on shades of black to make shadow. I'm not sure if there are pupils in her eyes, but I do like the effect.
