Very good shots. It's always a bonus when your model has such a beautiful smile. I like the third one the best, as your model's expression looks very natural, as opposed to the first two which look a little forced.
Thanks for the comments. I was pretty pleased with these shots so I'm glad I received good feedback. These were just with an SB-800 through a convertible shoot-through umbrella.
Camera settings are:
1/200 sec @ f/4
Shot with a Tamron 17-50 f/2.8 lens
Flash power set at 1/4
I would've loved to get the sky/background darker but with I just couldn't, I was shooting at my max sync speed and was unable to get it darker. I would've loved to play with settings a little more, but we ran out of time...shot this out in my yard in between the bursts of rain. It was a terrible weekend but I wanted to get some shots so right when I popped off a few, we had to pack up cause it began to rain again lol.
Here's a lighting diagram.
There's also a run-down of this shoot on my blog, the links in my sig.
