Thanks so much everyone for your comments...
The color version has nice colors indeed. I worked the colors of all these versions in LR and then I adjusted with mask the light and contrast in the reflection. It was taken in December last year. It was nearly mid day but the sun was beautiful that day, like early morning...
About the bright blue in the reflection, it was a side effect of my treatment with the reflection. There was a bit of blue in the reflection since the girl jacket is blue so at the time I work with contrast the blue brightened a lot more. The same goes for the red in the boat. I have desaturated those colors in the original frame in color above.
I do agree about cloining the bright spot at the left low corner, I was more concerned about other details and I didn't see it.
The sepia version is a treatment I am working with, it is not made with grayscale but just working with colors.
All of them have a dramatic contrast and brightness to give a bit of more light. I wanted to try this also in this picture. I am happy you like the color version.
About the crop, Pat. I took less of the trees and more of the reflection because the trees were not beautiful. It was taken in Winter and then most of the trees are naked, and that would have darkened my picture. The reflection was the only element I had to give light and interest.
My focal length here was 400mm, I was too far from the scene, to make another composition. If the trees had had beautiful light, I would have played a different composition and place them in the lower right third as another option. About a centered composition... It doesn't look bad. I like it, and technically probably better than the square format I am working or the original composition. But somehow, it doesn't deliver de message I want to give by isolate them in one corner of the picture.... thinking that any place could be a good corner for them to work their own buissiness, without taking care of what is happening around them...
Here is the original frame, I had this idea when I was taking the picture.
