Nice image Manos! I really like the bg, reflection, sharpness and exp. The reflection of the highlight on the bill is very distracting however, as it is blurred into a vertical line! Should be easy to reduce this to a smaller and less bright artifact, which would improve an already fine image!
Sweet image - love the water ripples in front of the duck's body. Agree with the comments on cropping and removal or reduction of the reflected bill highlight. The BG can use a bit of NR.
