Thanks, that's what I wanted to say

Hm no, it's because she's "grinning her teeth" (hope is the right word), as for the mouth (lips) is same color as the normal pose (she doesn't use a bright red lipstick like Tanya ).

Oh, got it. The bottom teeth just looked a little too long to me. I think that if someone's mouth is open that wide, some of the bottom gum would show? But I definitely see it more as teeth after it's been pointed out, so it might just be me, lol.
