Thanks, BAM, Fluister, Krule, and Bloodfather!
Krule, I really like that idea. Unfortunately I'm not sure how to pull it off. Since the patch is so small, you'd either get a tiny jolly roger or just a small part of the skull. Not sure they're be enough for people to know what it was supposed to be. Too bad, because it's definitely a cool idea!
Bloodfather, yeah, I'm actually using a mix of Violet Red and Dark Elf Highlight (a cool grey). So the result isn't quite as vivid as a pure violet red, which is what I prefer for this figure.
Another quick update. Over the weekend I finished off his hands and then did the cloth wraps around his forearms. Still have some stuff planned for that cloth, but didn't have time to completely finish it.
Here's a close up of the arms/hands. This should give you a better look at the color shift from green to purple on the elbows and knuckles. Of course on a normal human I'd just use red glazes for that sort of thing. Over the orc skin though, I think using purple glazes would take ages, kill the highlights, and still not produce the bright color I wanted. So I had to do this with opaque layers and then blend in the transitions back to the regular skin.
