Good, balanced composition and a really good subject.
I like the shutter speed you used.
I prefer it when there is still some detail left in the water and i think you chose wisely.
The only thing i could suggest would be if you had chosen a tighter composition where the leaf was more dominant in the picture. I think that would have been a much stronger composition and might've made the picture more impactful.
Apart from that, it is entirely wonderful
