You chose a panel where her face is in shadow, she is in a dark submarine. But look, right in that panel, you can see she has BLUE EYES. It is not impossible for a person of colour to have blue eyes if they are of mixed race in particular, but it is not very common at all. but anyway, I can play the image game too. From 3 separate artists.
^^this one has the same complexion as Freyja
I am sorry if you thought she was a POC and that was part of the appeal for you, but I am just not seeing it, she is white. And it's one of the rare times that's a good thing, because yeah, changing her race when she became Thor would be pretty tasteless. But as it stands from what I see, only her hair has changed colour.
