Good series overall.
A few comments intended as constructive critique.
On one the combination of angle and proximity makes her appear a bit bug eyed....flower on her head looks blown on my crappy monitor. Like the light. Take some of the yellow out of the background.
I like the idea for two. The foreground elements don't really add to the shot, the apple she is holding has a pine needle across it, her face would have been better faced up to the sky a bit more, and if the shot had been taken from a just slightly higher viewpoint. This shot has a LOT of potential, like the concept. I like the light.
3 is more of a snapshot, but a cool snapshot.
4 is the best of the series, for me. Creative shot, nice angle.
