G'Day Lies
Your sculpt is coming along great. The clothing looks awesome. I especially love the front of her top.
I am by no means a professional but here is my opinion.
I would change the face a little bit. Think about where the skull comes through in the face. Like what Jeremy has done. He has added a bit of a brow which you can see on the edge of her face. Also I would hint a bit more at her temples - bring them in a bit.
Her cheek bones are good but I would soften up the line just a touch near her ear where her jaw bone would run down.
I like what Jeremy has done with her cheeks but you could also keep a bit of the underside of her cheek bones if you wish.
The lips at the sides where the opening turns down could be brought in a bit and the skin on the edges bought out. She looks like she in smiling in the sculpt so if you look at your own mouth and smile you'll see that it stretches the skin around your teeth and the cheeks start to fold over the mouth just a bit and you get the fold from the nose down to the edges of the mouth. I hope you understand what I am saying I am having trouble explaining what I mean.
Maybe you could also lower the point where the chin starts below the mouth as well. Make it start roughly a third of the way down.
The ear looks good but some anatomy is wrong (I will use the anatomical names for this to try and make it clearer).
The leg of the helix (where it ends inside the ear) shouldn't fold forward like it does at the end. It should continue around, forming an exaggerated question mark that turns in on itself and ends at the anti-helix.
She also doesn't seem to have a Tragus (the hump at the front) or an earhole but its hard to tell from the image.
I would deepen inside the anti-helix to bring out the Anti-tragus
more. There is an image of an ear with the parts here

Her neck behind her ear looks like it bulging out a bit. It looks like Jeremy has fixed it a bit but I would also bring it in a bit more up the top.
Her hair line is very straight. Bing the hair just above the ears forward. You could also give her sideburns. They can be tied up into her hair like the rest of it but where you have the hair starting in this area is too high making it look like a wig.
Also next time if you upload a front and side view of her face as well it may help to give us a better idea of what you can fix.
I really hope this helps
