1. is under exposed a bit and the subject doesnt really hold me. Its flowing water traveling down a small little drop.
2. Dont care for at all. The conversion to B&W is a little harsh.
3. Is pretty centered as far as composition goes but it works in this shot.
4. I personally would have moved the horizon up a little in this shot to around the bottom thrid of the shot.
5. Nice shot. A little stark I wish there was something for a subject in the shot. The shot overall is nice. I like it because it is not something I get to see at all living in Upstate NY.
I really like #1, but right where the water flows over the log there is a stick standing up that bugs me. The branch in the foreground isn't that big of a deal for me, just part of the natural surroundings.
#2 I don't care for - just seems uninteresting to me.
Love #3 & #4
# 5 - I would like to have seen a bit more of the sky, but still a nice shot.
