This is a very pretty place. Most motion long exposure shots with water are from the lower end with the water coming to the camera. This is a nice change from that perspective, and the colors in the leaves are sweet to see.
The contrast here is marvellous. Deep rich greens and dark shadows are wonderful. Long exposures of water is something I've yet to try and looking at your shots makes me eager to get out there and do it.
I love the movement shown in the water on this one, Beautiful job with that, I would hawever like to see the leaves cloned above the rock on the left that are moving. I just find that ditracting and taking away from this beautiful scene.
