The upper image uses V4 transmaps on the brows.

I'm finding the same thing as far as eyebrows goes and with some eye makeups. I'm also finding that eyelash transmaps with straight lashes as opposed to curved ones seem to look better. Also, brows on the V3 head texture need to be quite arched, otherwise they seem to get straightened out on Antonia's head. As you said, some textures appear to be made for remapped Antonia, and others not so much.
