You call this poor lighting? I think it's nice and soft.
If I may give a piece of advice: clone the area next to her lip. At a quick glance it almost looks like she has a mustache, and then my mind starts thinking "TRANNY!". If you fixed that, this would be my favorite picture of the series.
I count 14 portraits in this series so far.
12 of them have something in common that I think makes them 'work' much better than the other two, anyone else see what I'm on about here?
Agree! This is not poor (my taste). With a bit of white balancing they should be quite alright.
And if you want to keep the background (for the sake of the mood) you could use the new selection tool called "focus area" in Photoshop cc to select your subject, color grade the skin tone to taste and apply the mask. The tool should be very effective since you have nice blurred background.
