This is an excellent photo Dan. I love the texture that you have achieved in the uppermost falling water,so much so that I wish that it had extended right across the entire print. But to be fair this is a minor quibble and on a site where waterfalls are a dime for a dozen yours is outstanding.
I'm not a fan of cotton candy water, but here it works very well...in tandem, I suppose with the ice. The flowing water is gorgeous, and wouldn't look this way at a significantly different shutter speed. My only quibble is the little sliver above the top of the falls which I wouldn't have included, but overall, this is nonetheless a major keeper!
