Tony,
Now this shot I like a lot. I love the color of the water, it makes great contrast to the moss. I always love when the rocks overhang the water like this, it makes for a more dramatic effect. It makes such a sharp line between the motion blurred water and the supper sharp mossy rocks.
I know you are into tight crops these days, and for the most part I have agreed with all your crops. But in this case, had you stepped back a tad, would you have been able to see rock in the lower left? It looks like the stream is trying to exit there in the lower left of the frame and I wondered if it is just a bend in the creek.
