This image is quite sharp but very busy. it's hard to find an element to focus on.
However, at full size it has a very abstract feel to it, especially the bottom half of the photo with the reflection : colors are soft but makes an interesting blend, and the little touch of blue and green do give a nice depth.
If I may make a suggestion I think the picture would be more interesting if you cut out the top of the image and only kept the bottom (make it like a panoramic). The tree branch (and it's reflection) is something we can focus on and it would give you a more balanced composition.
Nice shot
