Could use some work.
As you say yourself, its horribly unfinished. The background makes no real sense, things further away should be blurred more, not sharper; Apart from these three trees there really is not background, and I think it might have been better without any background at all. I like how you tried to have some movement, but its inconsistently applied. her face should be a bit lower (or she has a really long chin).
Other than that there is not a lot I can say bout this as it is right now.
