What color do you have in the area of the eyes?
Where the eyes are on the texture (and some actually paint eyes here, is the mucus membrane of the eye socket.
If you make this area a color similar to Lacrimal, that should be what you see.

Lashes transmaps? Good is a matter of taste. But it seems to me that quite a few of the free textures for Vic also come with lashes transmaps.

If you have the skill to do it yourself, go for it. Only Mother Nature can take the skill away, once you have it.

For Vic the reason that the lashes have so many instances, is that each has two layers. For sparse lashes, leave off one of the layers.
