I guessed right away this was your photo. Did no one else notice the hint of genitalia? I'm not complaining, I just think it's your thing to push the edge. Also the photo is highly competent. I could believe it was taken from the pages of Hustler magazine or some similar publication, while most entries run the gamut from artistic to bourgeois.
The smoothness of the skin offers a good juxtaposition to the textured foliage but although I've given a decent score of 7, I think this could be improved; getting a model in the landscape like this is such an opportunity but perhaps anonymity was important. The close crop to the head does hurt your composition a little.
A more shallow DOF would've helped this I think, there's an awful lot of messy distractions going on with all those twigs and things. I also wouldn't have cropped it quite so close to her head. She has a great figure, the exposure is good and the focus is clear, overall though this isn't a stand out entry for me. I don't know if the skinny tree trunk we can see between her legs was a deliberate angling to include it in that place or not, if it was then I feel it should be funny but it's just a bit crass; if it was accidental, watch out for such things next time!
OMG the only thing I can think of is TICKS!!!!!!!!!!!!!! eeeks..... Actually very nicely done, I don't recognize the butt, but the boots remind me of someone!
