Hi Akos, Nicely colored ,muted backround with an interesting subject.Good job with the flood effect but I would have preferred to see the whole reflection. If you look carefully around the top half of the image I noticed a number of cloning artifacts. Not hard to clean up...
I only reworked the jpeg and selected BG with magic wand and used a gaussian blur. Then flooded as per Dave's suggestion and cropped so it is not symmetrically framed. I know the bird has a slight halo, but that is due to the selection and blurring.
