Composition is very good especially in cropped version but in an attempt to grab the shadows, a lot of high key detail has been given up which is a shame cos I would like to have seen the two boats more clearly and possibly some texture in the mist.
The trees are in shadow cos I know this place at this time of year is a huge contrast challenge which suggests shooting it BEFORE the sun rises might have reduced the dynamic range sufficient for the camera to capture it all.
Digital cameras have perhaps 2 to 2.5 stops of dynamic range above the mid tone (will record white cloud & retain some detail) and 3 - 4 stops of dynamic range below the midtone (record some shadow detail before going black).
Forget what the manufaturer says cos they are all telling stories.
This scene has at least 5 to 6 stops of dynamic range which is beyond your camera sensor if you set the shadows about 1 - 2 stops below mid tone which is what appears to be the case here.
I hope you had some more bracketed shots cos you could make a perfect scene here and give up some shadow detail without losing any impact.
These types of shots resonate with me which is why I spent so much time writing this.
