The first one shows some potential - what with most people looking intently at the display. The lady in white in particular almost looks like she has an "Oh My God!" expression going on, even thought there's nothing in the display I can see that would be at all suggestive or controversial. The problem is that the artist(?) is interacting with you the photographer, and not with either the other people or her art. The guy in the bright blue shirt in the background also draws attention to himself - maybe that shirt could be toned down a bit.
The other pictures are really just snapshots.
