and this is my best attempt at dead (or undead) with the same 2 spots but the IBL at 8%.  i  haven't bothered looking for eyebrow textures to go with either of them, i could go even lighter and maybe higher contrast with the skin, and just generally, there are people better at this than i.  but i think  it's not bad for what's basically 9 different tries, including messing around with the lights.
