Very nice capture of a long exposure and controlling the light. Nice coloration without being over saturated. Only problem I have is that it just lackst that *extra* oomph.. that little something that puts it over the top.
Very nice. It's a bit contrasty in the area of the rocks (I'd like a bit more detail in the shadow areas) but the blur of the water is quite nice. It seems a bit overly white at the pooling point of the waterfall--almost as if that area had been overly burned in--it has an erased appearance to me. Maybe if this were framed so as to leave some space below this pooling point it wouldn't appear as odd as it is to me now.
It's a nice shot but I think it would benefit from being in B&W so we can concentrate on the stream and textures, rather than the fact that the top half is so much more vibrant colour-wise, which is the first thing that strikes me about the photo.
