Looks like a lovely spot. Your exposure seems quite good too. The only thing that I would suggest is to play with some different perspectives to get some interest in the subject - the bridge just seems a little flat and acts as a separation between the water and the trees instead of complimenting the image. The bridge would make an ideal lead in if viewed from a more acute angle.
A nice setting, but I think a spot of color would really make this image pop. A woman standing on the bridge with a brightly colored parasol maybe, a child walking across with a toy in hand... some little zing of color.
