The models are for play, I have a fair amount of bloodletters to go through. I took some of the tips from here and from some videos online and tried to apply them.
This is what I came out with for a final / semi final bloodletter.
I did a light dry brush on the bumps and spine with Astorath to see if I could bring them out just a little bit. Added another wash of red and another light drybrush after.
Toenails I found hard to get a good gray color, I ended up using Eshen with Dawnstone highlight then washed with earthshade but it made it almost black again. So I just did a little white with another wash to tone it down.
The horns were probably the most difficult, I had no idea how to make them look good.
