The image is particularly intriging with the various paths of the water entering the frame pretty much from the same direction, then flowing out at different angles. The distortion of the bottom vegetation is lovely.
Despite the ‘heavy post-processing’ you mention, this little scene looks quite natural to me. Seems you chose the right shutter speed to show the flow of the water while retaining the subtle greens of the stones. I also like the diverging and converging streamlines in this particular angle of view.
Stunning, especially on the full-screen setting. To my untutored eye the flow could be in either direction. I’m guessing it’s left to right, but the impression of a “downhill” flow R to L in the middle of the right side plus the suggestion in the upper vegetation (clinging to the stones?) of R to L flow leave me pleasantly puzzled!
