Specifically talking about the face; The biggest issue is with her hair, that is her hair line is so far back it appears like she's going bald, she has no eyelashes, and her eyebrows are almost non-existent. The philtrum is also too well defined, and the chin a bit too large and bumpy (turn down the normal/bump noise there). The lips are way too flat and dry looking, with an the upper ridge going too far towards to sides (it should fade earlier when moving away from the philtrum).
The body lacks definition in terms of bones, muscle, and skin folds, and the material lacks SSS. The body freckles are rather excessive too with weird distribution (most of those would be on areas someone exposed to the sun a lot, but even then I doubt it would look like what you posted on anyone younger then their mid-40s). The pelvis, ribs, and knees stand out as needing work from the front, and the back...doesn't seem to have any definition to anything at all other then the spinal crease (which should be interrupted at the base of the neck).

I'd accentuate her rib cage silhouette, etc.
