Hi Khonner! Just a quick drive by here. lol! I love the Reaper triads - especially skin tone ones but there's one color that doesn't fit that Jen Haley recommends for flesh tones. It's called Ashen Brown but Reaper was going to kill it off until Jen protested. It's an HD paint now. But some vendors may call it by a different name, unfortunately, I can't remember what it is off the top of my head. Anyway, the number is #29831.
This might seem a funky color to use for flesh, but used sparingly (on healthy human flesh) in the deepest shadows and a bit more on unhealthy flesh, again as shading, adds a fantastic "cool" tone counter to normally all warm regular flesh colors. It took me a bit to get used to the technique, but the more I try it, the more I like it. It really helps add some counter and pop without resorting to a wash. Anyway, just thought I'd toss that one out there for ya.
You're work is looking very nice! Keep it up!
