that's some heavy post-processing there. the effect on the water is great (not so for the sky imo) but there's too few of it. if you go for a re-shoot, try to include more water and less grass in the foreground. just my thoughts.
I like the guts of this photo. I'm not a fan of overly done post processing. This in my opinion is way too much. I like the less is more philosophy. This might work well as an abstract painting.
