Hi. Just one question; don't you think, that the plan you used id too big ? She is hardly visible among this trees. The portrait is IMO to much a driving license shot, too en face and not very happy. She is drilling with hes eyes the viewer.
In #1 I think there is too much bright stuff in the background and on the tree she is leaning against.
Her face looks to me like she is facing into a bright flash (note how bright her hands are)
I would fix all those things (and move the big tree)
