The smooth/obtuse nose-lip angle that the MH caucasian mesh has by default drives me crazy too. And I suppose it's only partially a topology issue; the asian mesh has more of the nose-lip crease than the caucasian mesh does. It's just that it's far from being the default in white people, as seen in your guy in the reference photo, and I made a target to fix it but it really should be a default feature IMO.
(my nose is the sharp crease kind, and seeing the default white female mesh having such an extremely obtuse angle, I have to suppress the insecure part of my brain; is the MH ""average"" far off from reality, or is it actually part of the ideal for female beauty that I somehow never knew about??? But I'm really getting off topic here... I've turned this thread into a general "complain about MH topology" thread)
Another nose feature MH lacks is nostril rotation to the side; you can pose the nose that way but it's not a target. I thought it would be easy to make a target from the posed mesh, but when loaded in MH, it only pinches the nose, and doesn't rotate the nostrils.
