I like all these Jon. There's something about the third that makes me smile and yet laugh a bit at the same time. I think you could do a great black and white conversion with #1 and I'd love it even more
actually, i tried these all in b&w and figured, again, i'd go with color because of the season. btw, my conversion didn't do the first justice. you can have a go if interested.
Good shots, seem to be seeing more people pictures lately. The couple in the last picture must be uncomfortable has to be a new spring relationship to put up with that awkwardness .
