Since you asked for critic, here goes, not that I think I can do much better. The compo looks good to me the natural framing is great. I think that it may benefit from a slightly longer exposure. It looks a little underexposed (but that may be my monitor) For these kinds of shots I try to shoot either early morning or late afternoon/evening to avoid bright harsh light that can burn out the highlights. Overcast can work too but you loose a bit of colour saturation. I usually do several different exposures from 1-5 sec depending on how fast the water is flowing. Im not sure layering this would have any real benefit other than to maybe adjust brightness contrast. I like this shot and think it is a good entry for the challenge LP
