Fixed the eyebrows, and I think I found out what's causing the seam under her shoulder. It doesn't appear on a color render for some reason, but it's an incompatibility with Golden Palace gens and vellus horizon. They both add shells and even if I turn off the visibility of the GP shell on the torso, I think that the 0.001 offset on the vellus hair causes a shadow to appear. Not sure how to fix that because if I make it smaller it overlaps the GP gens and her gens appears to be a mess.
Again, no smoothing, no postwork.
