Wonderful photos! My favorite is the umbrella one, but almost of the others are great, too. (I don't care for the black dress in the black chair one that much. The red dress in the black chair one is good, though. Maybe adding another effect to the former would get it looking a little better?)
Also, was she kneeling just before doing the black dress in the black chair one? She has two red spots on the fronts of her knees. You might want to edit those out, as they are distracting.
Thanks for the thoughts. This was a shoot that I did to force myself to work with lighting totally different than my usual studio lighting. We had a great time, got some great images and I've definitely got some things I'd like to try out next time.
