Stunning photo you've shot there. I like the composition of it where the river leads the eye off into the distance forest. Where was this taken if I may ask? The reflections in the river are clear and quite vibrant and the varying green tones of the surrounding forest have been really well caught, although there are places where the details fuzz a little. Have you tried cropping the photo either side? - I know you'll lose the wide shot, but it'll focus on the gorgeously captured river and reflections.
