I previously posted HS Senior Lauren from her shoot at country settings, she booked another shoot for some urban settings. These are 4 images from that shoot when she was dressed in what she called her Red stuff! Thanks for your comments!
Your crops have lots of room around the model, especially above her. I hope that was to allow for different ratio prints. I think the final crops should show her larger in the frame and show less of the background.
I think #1 is the pick of the litter. It looks like your camera bag is on a chair in the reflection on #3. Teeth look overly white but they all look good.
Watch for background things poking out of her head (#1 and 2) and hanging "dead" arms (#1). #2 expression is too tentative, not quite settled in. Yes, a lower point of view would be nice. Closer cropping would be great. Incredibly beautiful model. Great color, exposure and lighting.
