Pondering Crock

For those who don't know, the woman on the left is name Grossie and she is wearing a veil. That's what that's supposed to be. The question though, is why it's drawn that way. It fits snugly to the bottom of her nose instead of hanging down as you'd expect, and even though it looks like it's supposed to be opaque you can see her mouth through it, with the result that it looks as though her mouth is actually on the outside of the veil. Not to mention that her mouth actually seems to be on the side of her face (directly below her eye) instead of at the front like everyone else's. Why? I just don't understand it.
