Not bad.
However, your horizon isn't level. Also, with landscapes, you often need to decide where to place the horizon line. It's sometimes difficult to decide where to crop. Here, whats more important, the sky or the reflection on the water.
I find the dense tree on the left uninteresting, so it could be cropped out to place the sun in more of a Rule of Thirds position. The silhouetted bare trees are more interesting. If there were more to the right, I would have framed it in that direction.
The color is great, and subtle.
Hope that helps
