I wonder if you haven't sacrificed too much, in fact all, detail in that foreground bottom left area in order to capture those reflections in that water. There is some interest in those reflections, but perhaps you've concentrated oo much on them, and excluded too much of the setting, of the context? The sharpening seems a touch heavy - there's a suspicion of halo-ing around the branches, and some jaggedness in the lines too - slightly too high a radius? 5
