I downloaded your image just to try out a few things (as your photo's are ok to edit). Personally, I liked it best when it was cropped into a "panoramic" style photograph and then mirrored the photograph.
At first this looked weird, but the branches from the trees, sort of gives the photograph a direction. And gives (atleast me) a feeling of walking from woods over a bridge, and onto something else...
All in all, i liked the photgraph, I also agree with the others, that there is too much foreground, which makes the bridge seem tiny.
