Looking really well to my liking.
I have a feeling that her shoulders are a bit too broad, I understand, that she's quite buff, but in the concept it feels a bit less broad.
Second thing, that drew my attention, is her lips. Feels like they should be thinner. Such big lips make her feel like some African type, which she doesn't seem to be in the concept.
And thirdly, I'd make ears 20-30% smaller
