I like the composition of #1, but think the colour temperature is way too cool. Look at the handrail and notice how blue it looks.
#2 I also like, but I'd like to see how cropping a big chunk of the left goes. I think the clump of bright rocks there draws the eye away from the aflls on the right. And again it's a little too cool (not as much as #1 though)
#3 is a cracker. I like the diagonals and the wonderful backlit detail.
#4 doesn't grab me (sorry). It's very green (WB issues) and it's a bit noisy (as I'd expect at 1600 ISO), but the big minus for me is that he's on the path and so the shot has a less natural feel.
