Cottonwood fall

I like the color and exposure.

I think, from a composition standpoint, I might have gone with a portrait orientation. It would have avoided the awkward cropped tree in the top left corner, and maybe also trimmed out that (why must they do that?) chalk on the bottom left corner.

I like the framing and composition. My suggestion in these situations would be to take another fast shot in order to sharply capture the details that are lost from the long exposure - i.e. leaf/branch movement, and some of the water detail, and then blend the two images. Regards :)
