I have a gold cover also, but rarely, if ever use it. I think it gives a sickning, jaundaced look to the skin tone. As your model seems to have some Hispanic ancestry, the gold is definetly overkill. A white bounce would be more favorable IMO.
Second general observation, mind your backgrounds.
#1 - You and your model did well with the hand under chin placement. The line of the jaw is not broken or deformed by her pressing heavily upon it. I think the left hand would've been better if she bent it so that it is out of site. The little piece of hand/fingers sticking out is a distraction to me. The right shoulder and parts of her forearms are overexposed, but the backlighting in her hair is a nice touch. Personally, I think you went in the wrong direction for the reflector. As is, you have placed it lower right. This is causing 1) the catchlights to be in an ackward position (~4:00 o'clock) and has the nose shadow running upwards and creating an unflattering shadow on her neck. Placing the reflector higher and slightly camera left would have given a more natural light pattern with the fall of the sunlight IMO. Background: A couple steps to your left (if possible) would have eliminated the HVAC unit (or whatever, the grey box) as well as removing the tree growing out of her head.
#2 - The position of the reflector (low and camera left) is hitting her belt, neck and mouth, but is not lightening her face. This makes the face look underexposed, whereas, it should be the brightest part of the image. Even though you've thrown the background out of focus, the vertical elements are still distracting to me, as is the walkway.
All that being said, they are still pretty damn good, just a few things I noticed.
Beautiful model. Thanks for sharing.
