I immediatly wished I could view them larger and then found out I could. The small ones don't do it justice.
I like the first best as it seems to portray the power of the water more. I do wish there were a wider view so we could see the rest of the curve on the left. Might make a good pano stitch.
I don't want any crop of the sky as its power and the power of the river compliment each other so well.
