Why do her eyes look wrong in Dark Form?

is she born in game and became vampire through aging up?

if so the dark form may have different features to the normal form I've had it a lot with Vlads babies where they look like completely different sim in dark form

you can correct it if you link the forms and then slight tap her face features in normal form enough to tell game to replicate those on the dark form

i think her face length seems different in dark form that is also common theme with aged up vampires

You are right @Simmingal. Closer inspection does reveal a different face shape/length between forms. This is a brand new Sim still sitting in CAS. I will try the "Slight tap" approach because link, unlink, relink did not work; but a miniscule change might prompt the change as you have said...

UPDATE: Yep, that seems to have done the trick!! Thanks a whole bunch. B)

I also saw this with my two born-in-game vampires when they grew teens. The dark form was completely different sim.

Luckily you can copy the forms, eather normal form to dark form or vise versa. Might be a bit faster than tapping individual features to copy them, but I'm glad that worked too!

Her face looks sort of squished in the shot with the pink eyes. Don't know what's going on there.
