I really like the exaggerated foreground rocks in #2. They really being me in for more eye-wandering. Nice!
+1
But I also like the water flow of the third, although it's a bit too smooth.
The first is of "a bridge". Not having been there and not knowing the significance, I find the first "nice" but not compelling.
The rocks of the second are a bit over-exaggerated, but certainly, as Matt points out, more interesting.
