Well, you said the photo looked "off" in some way, and you said yuo coudn;t put your finger on it. And then three people in a row, with me being one of the three, took issue with the background.
I think the original had very distracting bokeh. The last edit looks the best to me,since it's a fairly convincing fake bokeh effect. The depth of field band is "faked"pretty well in the last edit. In the first,original photo, there were how many out of focus specular highlights??? 200? 250? All those small, OOF highlights, uphill, behind the little girl, were really distracting. The dappled light and yellow leaves are unusual,and only exist for a few days in any one year. It's a snapshot in time. Autumn 2009.
Completely eliminating the OOF highlights in the last edit has removed a lot of the distractions--hundreds of them have been removed in fact. it is an offbeat kind of look, an offbeat composition. Some day it'll be a treasured memory. As far as the 25mm's bokeh--I haven't seen any shots done with that lens. It's a fairly exotic optic--I'd like to see what it can do some day.
