One of the tweaks you have to make is mouth region. By contrast your model has a more distended mandible area. In order to match up the reference photo, the whole mouth area needs recessed more underneath the nose.
Its a scary adjustment, I know, but you can do it fairly easily using an adjustment with the proportional falloff editing tool. It’s meant for that kind of plastic surgery.
The upper lip is too large in relation to the reference. The bottom lip has good fullness but doesn’t taper upwards towards the corner of the mouth early enough.
Raise the model’s cheekbones. The cheekbone high point on the model mesh is in line with it’s nose tip. However, in the reference photo the high point of the cheek is slightly below mid bridge of the girl’s nose.
When the mouth/mandible area is recessed, it should also help define a more hollow cheekline from bone to jaw.
The eyebrows on the model mesh need to come down nearly half the given distance towards the upper
Regarding the model’s eyes, they are too far apart. Not greatly, but they need to be brought closer towards the nose bridge. For reference use the corner of the mouth and draw a line upwards. On the reference pic, notice the corner of the mouth is under the inner edge of the cornea. On the model, however, the corner of the mouth is not quite under even the inner tear duct.
The eyebrows and lashes came out surprisingly well. Great work.
