Images 1, 2, and 4 have some great subjects, color, light, movement, and structure - and very well seen. Aside from some framing issues - the use of the pseudo illustration/subtle HDR effects is cheesy/cheap and doesn't really add anything to your great captures. I would ask yourself do these post effects draw attention to and support/strenghten the "elements you've captured" or does it just simply draw attention to "itself"? I would say easily the latter. When you have photographic images that have great "documentary" content like these, most of the time it's best let them do the heavy lift if you will.
