The delicacy you have put into the outlines, character and detail gives this image the aura of the mystic. She looks like a shaman with inherited powers and the eyes are telling like she has perhaps a tribe to protect. I don't see evil in them. Powerful indeed, but with the knowledge how to handle them and the sense to keep the balance as well. An inspiration and stimulus to get myself doing research for the times before the antiquity and its empires.
I've said it on FA (where I'm mostly at), but I'll say it here, too. I am completely chuffed by this, stunned at the level of detail and accuracy, and beyond pleased with the overall effect. Epic, indeed.
