Thanks for opinions to everyone of you.
Yes, altaught water is quite clear there is strong brown tint in it. It got stronger during pp but i desaturated it quite a lot. Combination of brown water and wet ice , made ice very brown in real life too.
I did only long exposures this time, and changed water almost black for drama effect.
That black water look worked really well in these images, sukotin. Beautiful scenery, nicely done.
