my Precious...

First, beautiful subject.

I immediately notice the whites under her eyes. Techniques I have read say to avoid whites either all on one side or all under or above the eyes.

Looks good to me man. Don't even worry about settings. Settings mean nothing. Reason I say that is because sure you took that photo at those settings but I could take the exact same photo, someone else could take the exact same photo but all are settings are totally different.

The background is nicely lit up and with her hair being dark it isn't getting lost. Some people would of thrown a rim light on this but there is really no need to.

How ever 3 things you could possibly try if you want to lighten it up just a tad.

1. Lightroom > fill light

2. If you have another flash could of placed one lower pointing at her face on really low power.

3. A fill card. I used a bunch of 8 1/2 paper taped to a piece of cardboard and usually hold it under the models face or to the side to just kick in some extra light.
