DEFINITELY get paper. Don't mess with anything else.

You really need to move your lighting in closer and dial down the power a bit. I'm sure it was close already, I'm only talking fractions of an inch, but more importantly that reflector just needs to be a tad closer. Not sure what you're working with, but it is reflecting nicely just seems to be far from the subject for the material of the reflector. I mention this only because of a couple of thoughts:
1. Dial down the exposure ever so slightly, if not a 1/2 stop than a 1/3 stop.
2. The shadow under her chin can be lightened up ever so slightly.
3. Her bottom lip is catching too much light while her upper light is catching barely any (in comparison)
4. Camera right is getting a significantly higher amount of light than camera left, look very carefully and you'll see a significant line of color tone change. Not noticeable to most, but it is surely there.
These all could be related to the distance of the reflector, as well as how it is being held. For all I know, maybe you have the reflector too close and it is causing the same problems. Not very likely, but plausible.
Other than that though this is an excellent shot! I really do love it, than again it is right up my ally. Simple, clean, and powerful.
