Nice shots, cute chick.

Maybe slightly rotate the first one, and crop it to 4x5?
... exclude the foremost tree on the right edge and take the rest off the left side?
I think that would give a little better comp and put a bit more emphasis on her.

Edit:
Of the second set, I think she gets a little lost in the first one.
The second is nice, and she looks super hot in that dress... but I think a second light to rimlight her would help separate her from the background.

Overall, nicely done.
