The first image is a well spoken political image... Very powerful for me the way you've set the foreground and background subjects... The second dunno about the feet, not sure...
#3 has great saturation, good lines and terrific interest, maybe just clone or crop out the log(?) intruding in the BR corner... Another powerful image with the perspective under the bridge and that terrific sky...
The last one maybe a step to the right with less background stuff on the right and some more bridge??? Just rambling, thinking after the shot's always easier eh?
All these have great color saturation...
