You did what the model wanted? She was paying I take it, first spotted in portraits section.
Number one yes agree flat and non dimensional but do not understand the high sided jacket on neck, unless it is to hide the fact that it looks like she has lines or wrinkles on the neck from the B&W full face on shot.
Number two again personal choice but bleach, streaked hair seems to drain skin tone and seems to be forcing eyes wider, perhaps a little more direction from yourself in next session. Agree with the lights in eyes slightly distracting and agree that model in two shows skin flaws around mouth that could be edited out, lopsided lips and lipstick perhaps too over the top which also adds to showing these flaws.
