It seems that getting the larger value shifts correct will be much more important than those smaller areas you were asking about.
Take a look at the monochrome version of your painting that I posted just now, alongside the reference and -- this is really important --squint.
The face in the painting lacks a three-dimensional quality because the values are much closer overall than what the reference photo shows. The left and lower parts of the whole head need to be darker to create a sense of roundness.
The same is true with the overall value of the bodice of the dress. Because the plane of her chest is vertical, and even facing downward slightly, it is much darker than the upward facing plane of the skirt.
I think that getting these large value masses correct will make a very big difference in the painting as a whole.
Squint, squint, squint!
