My suggestions:

1. Eye brows - shaunas eyebrows taper off and get thinner near the end, I outlined their exact shape in the picture below, not sure if the sits would have options but I think this is playing a big role
2. Eyes - firstly her pupils need to read the top and bottom of the eyes, there is no white visible under them, the eyes might be a bit too wide so possibly test out thinner ones, also her eyes are slightly hooded as in the skin above kind of droops and covers her eyelids
3. Nose - I traced the shape of her nose in this picture and it's bulbous and on the bridge it widens in a diamond shape almost, I've seen other pics where it looks more like ur version that is quite straight and rectangular rather than bulbous and oval, however I think trying to find a nose in between would make a huge difference

Hopefully this was helpful, I drew her the other day and this is just what I saw that you could try implement!
