Look, everyone has their opinions, some say them out right more boldly than others. If you post your shots here, you are open to people to post up their impressions, both good or bad. You have to understand that when you post, because if you post and can't take criticism, why post at all?
Yeah your shots do need work. Sharpness is not as important as composition, what are you trying to tell viewers by the shot you took. There are shots that work just as reportage, a collection of various events that happened at that place and time. Other shots, like some of the ones you tried to make are meant to be portraits that show the mood of the whole thing with peoples emotions that could add up to the whole picture of the event.
Besides the lack of sharpness and composure in most of your shots (which are really just a few technical flaws you can easily fix), the main reason they're not significant is the fact that they don't really capture anything. Ever heard a song someone wrote and it had absolutely no meaning? Yeah. Empty.
