I do not understand the above comments. It is the light that makes this image. Without the sparkles on the water the image would be much poorer. Apart from which, you obviously intended to post the image like this and so it should be judged on the value of the image, not on personal taste. If it is any consolation I get a stream of 'too dark' comments on my images. It is just because you have posted an image that does not 'conform' to the mediocre average image here.
The low CI is just Caedes voting. Ignore it, and it definitely does not do justice to this image. I like the diagonal composition which balances the picture. Overall a very nice picture that makes a good background.
