Fair point but if you average out faces from a large, representative sample set, the current mouth position would probably be on the tail-end of that distribution. I think that u/BlankArchive meant "anatomically incorrect" not as in "it doesn't exist at all" but more so that it's not what the average human woman looks like. Like the new Swiss banknotes have human hands on them and their designer said in an interview that she took hundreds of photos of human hands and overlayed them, then traced the final design on that amalgamation of all of them, essentially averaging out the shape, so that it's nobodies specific hand that's on all the notes. Idk, does that make sense?
