No reason not to like it. Very peaceful and a great reminder of what must have been a very pleasant day.
If you want a suggestion... Consider cropping to 4x5 or 1x1 and in doing so, "moving" the brightly-lit tree from its central location to the right, reducing the dark forest on the right (and a bit of the left forest, too) in favour of the natural flow of the river to the left. Keep the one angled tree on the right though, with its base near the bottom-right corner.
