The leading line of the waterfall and the curved edges of the pond project a nice relaxed mood.
There seems to be a colour cast (magenta?) on this image. In camera I couldn't tell you how to fix this other than play with the white balance. In post processing you could adjust the colour balance slightly more towards green (opposite of magenta).
You made the picture with very hostile light conditions (reflections and bright sky). What about a polarizer ? Anyway the result, probably after some editing, was pretty good.
Excellent shot. You may consider bringing the camera closer to the ground next time, and capturing more of the trees in the background to round out the shot.
