very nice shot. I like the angle you have choose to take this pic. The reflection in water and sound made it look like a glass painting..
Nice. Just a friendly suggestion the noise in this pic is little too high, reduce your shutter speed like say 1" and reduce the ISO to around 300 - 400. I agree to your concept of higher ISO for low light, but there are other ways to capture light, like the one just mentioned above.
Use a tripod for more sharp images,
Last but not the least, Thanks for sharing... and welcome to TL
Nice place and pic.
