#1 - Nice capture, but I think a longer exposure (like the others) would have captured the waterfall better than freezing it in place. I also think this one is way oversharpened.
#2 - The water looks better here, but there is some motion blur which leads me to believe this is handheld instead of using a tripod.
#3 - See above. Even more motion blur on this one.
#4 - Best shot of the bunch. You can see some blur in the leaves and rocks, but it's not as noticeable as the others.
#5 - I think you need more motion on this one. When something is spinning like this, either stop it completely or use a low enough shutter speed to show the motion. You're somewhere in between.
All that said, in the future, please refer to the Critique Forum Rules and only post 1 photo per thread. Reference the others in your gallery if you want, but like Rick said, you'll get much better feedback by posting your best image and taking things one at a time.
