Nice, interesting image. I think it would have been better with less saturation. Just to nit - the grass seems to conflict with the texture of the needles. Take out the grass on the top right(different angle), and it would be much better.
A unique setting, but I have to wonder if there were a better angle for this shot somewhere. The far right half of this image seems to detract from the subject waterfall and coloured stones. The entire image may benefit from a cropping off of the top 1/4 and right 1/2??? You could also have crouched down closer to the ground and used the stones as a foreground bokeh. Just a few thoughts to consider. It's easy for me to make these suggestions, but the option may not have been possible for you in this situation.
