Not sure what side of the fence to sit on with this one… Its a beautiful scene and yes very tranquil. For me the light is extremely flat and maybe the exposure slightly under. Maybe a slight boost in saturation would help and a bit of anticlockwise rotation. The reflections are superb and think my main issue with the image is the quality of light.
agree with the above the light made it very hard for you to make a good job of this i would revist in dawn/dusk when the light is better good composition though..
