Probably just my monitor, but there is something wierd going on just above the horizon line. Not a big deal and may be compression artifacts. Nice cold, blue, picture.
What I really love about this photo is how everything is iced over..... great composition and well focussed.. the blue is on the warm side and maybe a cooler blue would have been a better choice.... still, a really good photo that suits the challenge and makes me shiver!
Great duotone. I might have done the border in the dark blue instead of black and the horizon line appears a bit pixelated, but very cool (no pun intended) capture.
Like a scene from Narnia, good choice of cold blue duotone. Maybe a slightly different composition based on rule of thirds might have worked better. I think I'd have liked to see more of the frozen ground as it has great tone and contrast.
