I like #1 - how you've framed in with the background.
#2 Seems zoomed in a bit too much. More light in the eyes could help too.
#3 Shouldn't the whole hand be in the frame?
#4 Showing the whole body (compared to #1) is my usual choice. Not sure I like the pose in this one as much as #1. A lower camera angle would place her head against the sky - an improvement.
Wolfr: Agree on the styling, it was also an impromptu shoot so we had to do with what she came up with. However I liked how the colors of her clothes matched with the surroundings in 1 and 4.
Working on that though, I set my goal for this summer to overhaul my portfolio a bit, with more work that would appeal stylists or local boutiques a bit more to lend out some stuff once in a while.

2: I could have used a little fill flash for the eyes or a reflector indeed. Being an overcast day, the light looked fine how it was, but seeing it afterwards it could use some more pop indeed.
2 & 3: Yeah, I tend to like to go quite close for portraits, which often involves some cropping of hands or other body-parts. Personally it didn't really bother me in those pictures, but I understand that opinions may differ.
4: Good point about the lower angle, I should do that more often.
And oh yeah, the model was a real natural beauty. Almost perfect skin. Barely any make-up and retouching is limited to an absolute minimum in these photos
